Mike, don't kid yourself that you can't be seen on AI radar. I have
picked up geese at 7 miles on my F86D X-band (10ghz)radar off Okinawa
way back in 1956. Our GCI radar picked them up coming inbound and
asked me to check out the track. I was quite surprised when I closed
in on the target and discovered it was a flock of 7 geese heading for
Japan about 30 miles east of the southern tip of Okinawa. You are
about 75% water and Xband resonates with the water molecules - so you
will show up as a radar target.
