I have set up several parameter files for different weather. See discussion
in seperate radar log entry.
For all parameter files:
LAT: 39.25 N
LON: 119.81 W
ALT: 1566 m
ID Code: 502 (ISS2)
BEAMS:
NAME AZ ZEN CODE CLUTTER ON 02-22-2002 (Friday)
yvert 13 0 22 a lot of clutter to far ranges
xvert 103 0 21 fairly clean
y+nor 13 21 38 light clutter to 700 m
y-sou 193 21 26 a lot of clutter to far ranges
x+eas 103 21 25 light clutter to 500 m
x-wes 283 21 37 light clutter to 500 m
Conclusion is to use: yxert. x+. y+ in 3 beam sequence.
