The antenna cycled through two 10-min
composite scans (one east, one west) and a
10-minute dwell parallel to B.
The composite scans were performed with
a variable scan rate that gives
constant ground tracking. The complete
cycle time was just under 31m30s.
Transmitter
mode:
Dual longpulses, merged. Although
the data are fully sampled
every 21 km, the resolution of
the pulselength is 48 km.
Range
integration:
The data were range integrated for
21 km up to 200 km altitutude,
42 km from 200 to 400 km
altitude, and
63 km above 400 km altitude
(although the best resolution of
the data is 48 km).
Time integration:
The data were integrated on-line for
10 sec, and were integrated for
processing as follows.
The dwell data were integrated
for 3m20s (200s), giving 4 records for
each 10-min dwell up B. The
scan data were integrated for 60s, giving
10 records for each scan.
