Improvements

• Increase automation – ground station front end

• Addition of a relational database - currently used to set-up requests for known targets and log requests sent.

• Variable buffer size – trade off between responsiveness and histogram variation

• “Science” products – FRP, Normalized Difference

Real time georectification

Good relative with properboresighting.

Elevation change and importance of a good DEM

Adding Algorithms

• Designed with this in mind – fairly easy but does require recompilation

• Database (somewhat spatial), meta-data, simple thresholding, normalized differences

• Would lend itself well to unsupervised clustering algorithms

• Processing time for “real time” turnaround varies with scanrate and buffer size selected. At a scanrate of 11sps, there 1.8 min., to 54sec. of processing time for 1200 and 600 line buffer respectively.
