I. INTRODUCTION
The nominally right hand circularly polarized 11.7 GHz beacon
transmitter on the CTS satellite has been monitored at The University
of Texas at Austin for the periods of its operation. The data presented
in this report cover the attenuation and isolation measurements made
•with a dually polarized receiver and rain rate measurements made with
a single tipping bucket rain gauge during the period of February 1978 to
January 1979. Reports to be issued later will cover the other two ex-
periments going on in connection with the one presented here. They are
(1) the adjustable receiver polarization experiment and (2) COMSTAR
attenuation and diversity measurements at 19, 28 and 13 GHz. In
addition, at the conclusion of the CTS experiment a summary report
covering all the data collected will be issued. The data collected before
February 1978 have been summarized in two previous reports. The
first of these also contains a detailed description of the receiver.

system are given in Table I.

Integrating over the rain rate distribution measured at the receiver
site from 5 mm/hr to 150 mm/hr gives a total of 480 mm. This
means that about 40% of the rain fell at rates below 5 mm/hr. Com-
paring the total rain and number of thunderstorms to their long term
average of 846 mm and 41 thunderstorms, it can be concluded that this
reporting period had close to average weather.
IV. 12 MONTH SUMMARY OF THE ATTENUATION AND CROSS-POLARIZATION ISOLATION MEASUREMENTS
The percentage of time the attenuation exceeded specific values is
shown in Figure 1. For example 10 dB were exceeded for 1. 6 x 10"
percent of the time. From Figure 2 it can be seen that for the same
percentage the isolation was less than 21 dB. The isolation is defined
as the power ratio between the co-polarized and cross-polarized channel,
or when expressed in dB:
CPI(dB) = Co-polarized signal level (dB) -
cross-polarized signal level (dB)
where the signal levels are measured with respect to some arbitrary
reference. In this case this reference was the clear air level of the
co-polarized signal. As shown in Figure 3 for 1.6 x 10 percent of
time the rain rate exceeded 55 mm/hr.
The distribution curves define statical relationships between the
measured parameters which can be used for modelling. For example,
from the equal probability pairs of attenuation A and cross-polarization
isolation CPI one can derive that the two are statistically related as
CPI = 33.4 - 13. 1 log A.
This equation represents the least squared error fit to the points indi-
cated in Figure 5.
The density function of the quantities A in the range 0 to 30 dB
and CPI in the range 10 to 40 dB was calculated from the data. From
this the curves given in Figure 4 were derived. They show the 10% ex-
pectation, median and 90% expectation of exceeded isolation for each
attenuation. For instance the three points at 5 dB mean that for

90% of the data collected had CPI better than 23 dB, 50% of the data
(the median value) had isolation better than 28 dB and for 10% of the
data the isolation was better than 33 dB. These curves given some
indication of the consistency of the relationship between the two
parameters. It should be noted that the curves are better defined in
the lower attenuation range where they are based on more samples.
The logarithmic fit to these three curves was determined to be:
10%: CPI = 42. 9 - 17. 5 log A (r2 = . 94)
50%: CPI - 35. 8 - 13. 4 log A (r2 = . 89)
90%: CPI = 31.5 - 12. 6 log A (r2 = . 90)
2 2The value of r is a measure of the quanlity of the fit. If r =1 all
points lie exactly on the line and if r =0 the points were randomly
distributed. (For the equal probability fit r was . 99). The curves
defined by the above equations have been added to Figure 5. It is
apparent that the equal probability curve predicts less isolation than
the median data curve, a fact related to the particular shape of the
density curve.
To estimate the contribution of ice depolarization to the isolation
statistics, Figure 6 shows the percentage of ice depolarization in the
total depolarization events. The points were calculated by
Percent = (Time the isolation •was less than the abscissa
and the attenuation less or equal 1 dB)/(Time
the isolation was less than the abscissa ) x 100.

The interpretation of this curve is that caution has to be exercised
when using the logarithmic fits to the CPI - A relationship in con-
junction with attenuation statistics to predict depolarization at low
attenuations. The derived isolation statistics will need correction
as per Figure 6 to account for the contribution of ice depolarization.
The excess depolarization will decrease with increasing attenuation.
Also part of the data summary are Tables 3 - 8 .
Table 3 gives the distribution data in minutes. These were used
to draw the exceedence plots Figures 1 - 3 .
Tables 4, 5 and 6 gives distribution data resolved into time of
day of the occurrence of fades, depolarization and rain rate. While
the density of the data events is not uniform over the 24 one-hour
intervals, it is hard to make a general statement as to -whether events
are more serious at certain times than at others. The times are
Universal Time (GMT), which is 6 hours advanced from Central
Standard Time. Maybe it will be possible, when all the data collected
will be analyzed in this fashion, to discern if the probability of data
events is evenly distributed over all 24 hours of a day. Table 7 orders
the data events by their duration. It gives the number of events for
each threshold level and their duration. The data show that the events
with higher attenuation, lower isolation or higher rain rate tend to be
fewer and shorter. The lower number of events when the rain rate
exceeded 5 mm/hr for short durations is due to the fact that the rain

rate is calculated from the interval between accumulating . 254 mm
of precipitation. Therefore short durations of low rainfall rate are
not resolved.
The data in Table 8 were used to plot Figure 4. They give the
spread of isolation values for the measured attenuations.
The data for each month of this reporting period are presented
in the Appendix. Given are the distribution plots for attenuation,
isolation and rain rate and the same set of numerical tables as has
been included for the yearly summary, i. e. distribution tables, time
of day tables, the duration data and the isolation vs. attenuation table.
V. CONCLUSION
Attenuation and cross-polarization isolation data have been pre-
sented for a 12 month period. During this time the weather was close
to the long term mean. Fades exceeded 10 dB for about .02 percent of
time. With the same probability isolation was reduced below 21 dB.
The data events were not evenly distributed over the time of day,
however it is hard to identify a distinct pattern from the 12 months
data.
