The purpose of this report is to present the additional results of apply-ing the Point Scattering Model for radar image simulation toltree (3) newcases. This work is supplemental to that previously reported ' . The work was

sponsored by the U. S. Army Engineer Topographic Laboratories (ETL).

The results reported were obtained for four (4) simulations correspondingto four specific altitudes in the terminal trajectory of a guided missile(three of the simulations are new), each successively lower. The sequence of

four simulations was tested against actual radar data of the same sitevia the Correlatron*. The correlation tests showed performance ofsimulations produced by the PSM to be acceptable in three cases, and tobe unacceptable in one case. The unacceptable performance was explainedby geometric errors inadvertently introduced into the data base and wasnot produced by the simulation method.

A low cost, self contained vehicle navigation system was conceived anddeveloped. It utilizes a single gyro and accelerometer, and an odometer in asemi-strapped down configuration. Under this program, the system was testedin a van type vehicle. Performance (0.4% of distance traveled) was satisfac-tory over level, paved roads. However, for operation over rough and hillyterrain, design changes are needed to improve the performance.

20. ABSTRACT (C-thous - .vr ofel s N n--- ad Id.nWtIy by block n...be)

A flexible algorithm has been developed to meet the changing require-ments for generating terrain data from digital stereo sensor records. Thealgorithm includes an image matching procedure in which parallax componentsare determined by automatically correlating conjugate image features. Thealgorithm is adaptive and can handle various types of sensor and naturalterrain conditions. Reliability monitoring of the output terrain data is per-formed on the basis of the in-process analysis of local image areas. The re-liability measure dictates various strategies that the algorithm can apply

20. Continued

in image areas where automatic correlation is difficult.

The algorithm was implemented on a distributive network of paralleldigital processors. In this system, production speed is attainedbecause of the inherent parallelism of the modular processors. Flexibilityis maintained because the processors are microprogrammable. In this way,new sensor imaging characteristics and new algorithm strategies can beincorporated without disturbing the fundamental software and hardware

structure of the system. Production times for compiling a representativestereo model on this parallel configuration far exceed the capability ofgeneral-purpose computers.

Based on the benchmark implementation, a production system has beendesigned which incorporates a full interactive image display capability.This allows an operator to interactively monitor, control, and edit thestereo compilation processes by means of a stereo CRT display, keyboard,and trackballs.

The aims and objectives of this report were to collect and assimilate

information and synthesize data on the effects of atmospheric obstructions to

visibility. A large part of the total study effort involved an extensive lit-

microcomputers operate in parallel to perform the functions: (i) starimage centroid determination, (ii) star pattern identification and dis-crete attitude estimation (subsets of measured stars are identified asspecific cataloged stars), (iii) optimal Kalman attitude motion estima-tion/integration. The system is designed to be self-calibrating with pro-vision for routine updating of interlock angles, gyro bias parameters,and other system calibration parameters. For redundancy and improvedprecision, two optical ports are employed. This interim report documentsPhase I of a three phase effort to research, develop, and laboratory testthe basic concepts of this new system. Included in Phase I is definition,

formulation, and test of the basic algorithms, including preliminary im-plementations and results from a laboratory microcomputer system.

The Corps of Engineers and NASA's Earth Resources Laboratory conducted a joint

demonstration of the production of land cover classification data from LANDSAT

data. This report describes Phase III of the demonstration, in which classifi-

cation maps and data were- produced for two Corps of Engineer District Wil-

mington District, an area in the upper Roanoke River basin of Virginia; and

Jacksonville District, an area along the route of the Cross Florida Barge Canal

The report includes the Districts' evaluations of the accuracy and applicabilit

of the clasifications and cost information for Phase III of the demonstration.

The report also includes cost information for the application of inter-disciplinary analysis of aerial photography as a means of obtaining landcover and environmental data.

LANDSAT data may be cost-effective for identifying and showing the distri-bution of general types of land cover for large areas, although some landcover types may not be identifiable on a particular LANDSAT scene. Inter-

disciplinary analysis of aerial photography identifies and explains in atechnical report the distribution of land cover. The extra detail of thereport and the ability to ensure that specific land cover types are studied

may make interdisciplinary analysis of aerial photography cost-effectivefor limited study areas.

The objective of this work was to determine the reliability of a desert shrub,ARTEMISIA FILIFOLIA (Sand Sagebrush) as an indicator of soil depth. Near LakePowell, Arizona/Utah; Hurricane, Utah, and St. George, Utah, more than 480siol-depth-to-bedrock measurements were made in A. FILIFOLIA communities, intransitional, mixed communities, and in adjacent plant communities that didnot contain A. FILIFOLIA. It was learned that the presence of ARTEMISIAFILIFOLIA reliably indicates that the depth of the soil mantle over the bed-rock is greater than I meter.

20, ABSTRACT (C amt - revesem ebb N ne7 d Identify by block rnumber)

The objective of this study was to determine experimentally the feasibility of

using optical power spectrum analysis techniques for automatic topographic

feature classification from high resolution radar, panchromatic and thermal

imagery. A data base of radar, panchromatic and thermal imagery was assembled.

Radar and panchromatic imagery were available over the same geographical area

with the same scale and perspective. An optical power spectrum data base of

6,216 individual aperture samples from the three types of imagery was col-

lected. Included in this data base were samples over the same area with

different aperture sizes. Feature analysis and decision software requiredin addition to standard FACEL routines was developed. Using this software,features and a decision rule were developed for radar imagery that achieved90% correct classification of four classes of terrain. A quantitativestatistical analysis was performed to determine the effects of apertureand sensor type on the performance of the optical power spectrum basedfeatures. In addition, a qualitative analysis was performed in order topresent examples that illustrate signature differences between radar andpanchromatic imagery.

The following general conclusions were drawn from this study:

(1) There are statistically significant performance differences foroptical power spectrum based algorithms for radar, panchromaticand thermal sensors.

(2) No statistically significant trend is evident associating better orworse performance as aperture size increases that is independentof the imagery type.

(3) For a given type of imagery, there is a statistically significantvariation in decision performance that depends on aperture size.

(4) For the samples used in this study, the single best sensor is radar.It is presumed that this is because of the greater texture variationspresent in radar imagery compared to panchromatic or thermal.

(5) No single sensor performs best for all classes. The results of thisstudy would lead to the following choices for the detection ofparticular terrain types:

a. Urban - panchromatic

b. Water - radar or panchromatic

c. Agriculture - radar

d. Forest - thermal or radar

The results are reported from applying radar image simulation to produce simu-lated reference scenes of winter conditions for a missile guidance usage. A datbase was constructed of the Watertown, New York, test site and simulated radarimages were generated. The data base was prepared from historical data for an"average" winter at the test site. Simulated radar images were produced via thepoint scattering model and an empirical model was used for predicting the electromagnetic reflectance from the ground, its cover, and overlying snow. Copiesof the simulated radar images are included.

The results reported were obtained for four (4) simulations correspondingto four specific altitudes in the terminal phases of the trajectory of aguided missile, each successively lower. The simulated images have beenproduced for testing against actual radar data of the same site via theCorrelatron*. These tests have not been performed as the actual radar datahave not yet been obtained.

*Correlatron is a two-dimensional cross-correlation measuring device manu-

factured by Goodyear Corporation and installed at ETL.

The purpose of this contract isto investigate the test and evaluation procedures to be used with these new dataprocessing devices. Specific attention was devoted to the photo-DKDP and theliquid crystal light valves.From detailed experiments performed on the LCI.V, a spatially varying sonsitometr.andi contrast ratio and a voltage and frequency dependent sensitometry were ob-served. These issues were analyzed, modeled, and theoretically explained.

Complete sensitometry, resolution, and noise test data for the photo-DKDPwere also obtaincd. From these experiments, we found a field dependentsensitometry of the Se photo-conductor used in this SLM. This makes thedynamic performance of the device superior to its static performance butmakes interframe operations such as image addition and subtraction diffi-cult. A theoretical analysis of this issue was performed and a suggestionto decrease the field dependence by proper device doping was advanced.From these extensive experiments on individual devices, a general testand evaluation procedure for SLMs was formulated. Issues addressed weresensitometry, resolution, and noise. The appropriateness of the varioustest procedures for resolution and noise measurements to various specificapplications were also noted.

An extensive experimental program was also completed in which the photo-DKDP SLM was used as the real-time input transducer for an optical addi-tion and subtraction system, two optical pattern recognition correlatorsfor text and aerial imagery, and two optical signal processors for ambi-guity function computation. Comparison of the performance of the real-timeSLM systems to similar systems using film as the input material and com-

parisons to the theoretically expected correlation output plane data werealso included. In all cases, the real-time SLM system performed mostaccurately.

For a curved contour, the simplest invariant under shift and rotation is thecurvature. To make the curvature invariant to scaling, one may divide it by thelargest curvature or multiply it with the length of the contour; the multiplica-

The results of a study of four different hardened gelatin holographic recording

materials are reported. These are the dichromated, diazo, diazo resin, andsilver halide (sensitized) gelatins. The report concludes that of the fourphotosensitive processes studied, the silver halide (s 'nsitized) gelatin procesoffers the most promising process characteristics.

The silver halide gelatin process is a new holographic recording process thatcan be used to prepare phase volume holograms in hardened gelatin.

The process uses a reversal bleach that dissolves the developed silver

metal image while further crosslinking the gelatin in the vicinity of the

silver image. Upon fixing and with dehydration of the resulting gelatin

hologram, one obtains recordings similar to those produced by the dich-

romated gelatin process. This is accomplish with exposures on the order

of 200 to 500 PJ/cm 2 at 514.5 nm in a silver halide emulsion that

has a panchromatic response. Furthermore, because the hologram has no

sil, r halide present, the hologram does not exhibit the printout phe-

nomena characteristic of bleached holograms.

An electro-optical system for obtaining two-dimensional Walsh transforms ofcartographic images was developed. The system uses a plasma discharge device togenerate visible two-dimensional Walsh function pattern masks. The cartographicimagecy is placed in contact with the plasma tube, and the product of the maskand image is integrated with a single photodetector. The system is capable ofproducing 512 by 512 (262, 144), two-dimensional Walsh functions, and the samenumber of associated Walsh transform coefficients in about 14 seconds.

block of Walsh transforms (64 x 64) was facilitated with a system mini-

computer and a CRT display. A set of selected cartographic images andtargets were used to evaluate the system. It was discovered that most

of the significant transform information appeared in the lower order Walshtransform coefficients, and further that each Walsh transform pattern isunique in itself and can be distinguished from the others for a limitedset of well defined inputs. The dynamic range, the temporal response, andthe symmetry of responses of the Prototype Image Spectrum Analyzer (PISA)were found to be relatively poor.

20. ABSTRACT (Csaul . twu ,m m eo e 0 ,41 " a e eeep d I ditillY by block nusiber)

RADOT (Radar on Trees) is a system of FORTRAN computer codes designed topredict the radar return from a canopy of vegetation.

The system combines a realistic simulation of the geometry of the trees of aforest with simple approximations as to the physics of radar scattering withindividual branches and leaves.

DI FORM 1473 EDITION OF I NOV G9IS OBSOLETE 60 UNCLASSIFIEDSECURITY CLASSIFICATION OF THIS PAGE (Wren Does Entered)

20. Continued

Program TREE is used to generate a prototype tree, for example, an oaktree. A tree run is based upon a detailed input description and need beperformed only once for each tree type. The output is a tree model, des-cribed down to the level of individual branches and leaves, which can becombined with a "library' of previously generated prototype trees, intoa new library of prototypes. This new library subsequently serves as inputto Program HIT, the main geometry code.

Program FORGEN, the forest generator, combines user input with built-indistribution functions to place trees throughout a simulated forest area.The tree, itself, is one of the prototypes available from the library,scaled and reoriented by FORGEN. The output of FORGEN is a forestmodel which contains information as to the location, size, orientation andtree type of each tree in the forest. This forest model can be saved forall subsequent analyses involving this forest.

Program HIT uses ray-tracing techniques to establish the composition ofthe forest as a function of height above ground. The output of HIT is afile of single scatter layers. For each layer, there is provided a completedescription of the type, size, and orientation of all materials containedwithin. This completes the geometry portion of the RADOT system. Thedesired physical description of the forest is now available to MATRIX,the code which combines the geometry and microscopic physics data. The out-put of HIT may be saved and combined with several varieties of physicsdata.

The physics portion of the RADOT system is treated by Program LEABRA(Leaf, Branch). LEABRA is based upon the assumption that, for radar, eachinteraction with a branch or a leaf can be treated, on the local level, asan interaction with a finite, circular dielectric cylinder, or with a thin,circular, lossy disk, respectively. The physics of such interactions, andthe numerical solutions of the formulations so involved, are incorporatedinto LEABRA. The output of LEABRA is microscopic radar differentialcross sections, independent of the actual forest geometry. The output ofLEABRA may be saved for future combination with several varieties offorest description.

Program MATRIX is a multi-layer matrix code which combines the geometricforest description data with the microscopic radar scattering data to de-termine the overall radar return of the simulated forest. In MATRIX, thesingle scatter layers, determined by HIT, are treated one-by-one, start-ing with the topmost. The physical descriptions within each layer are cam-bined with the microscopic differential cross sections to obtain the over-all transmission and reflection matrices of the layer. These layers arethen successively combined, working

61

downwards toward the ground, into composite thicker layers. The trans-mission and reflection of the larger synthesized layers are obtained inthe course of this combination process. This continues until either theground is reached or the system converges. At this point, MATRIX providesa print-out of the determined return from the simulated forest.

It is concluded that the RADOT system of computer codes is a potentiallyvaluable tool to predict the radar return from a canopy of vegetation.It combines highly realistic simulation of the geometry of trees of aforest with simple approximations as to the physics of radar scatteringwith individual branches, leaves and the ground.

To date, however, RADOT has not been tested against any field data. Thiswould certainly be a logical next step to take in this developmentalprogram.
