PROFILER
ANTENNA ORIENTATION:
Looking along Y38 side is 110d, ie. y+nor (38) is 20 deg (E of N)
(Corrected for magnetic dec of +17d).
MODE: For ops plan to run in 3 beams with low and high modes.
15 Nov 2UT - 19UT, 23:30UT - Nov 16 19:30UT
3 beams, south and west beams.
Clutter may be a problem at times.
There is forest all around, Black Butte mountain is about
3 km for the north east (55d E of N). There is also sometimes
heavy equipment (trucks & loader) operating 50 to 200 m to south.
TEST 5 BEAM MODE:
To test which beams have least clutter, ran in 5 beam low mode
Nov 15, 19UT - 23:30UT. Some rain and some clear-air.
Processed that period with NIMA. Clutter algorithm found:
East & West beams similar clutter (~23dB), though east has greater std.dev.
South more clutter than north (~20dB vs ~5dB)
N & S saw a little mountain clutter (~1-2 dB) at about 3km.
South also had a little more noise & unidentified signal than north.
Decided to use west and north beams.
Nov 16, 20UT: back to 3 beams, low & high mode, north and west beams.
