what your sayingis radar absorbtion & dirrectablity is impossible?
send a fm chirp back to a radar unit and watch what happens
top speed is still determed by time lasp. 10 years have nothing to do with return signal if you don't get the same amount of return
you'll get a differnt reading .thats how 117 is "radar invisible"
yes your radar might pick up a bb but a bb will not have the return of a tractor trailer.i'm not say that don't have there use but to totaly rely on it would be rediclous .and it has no bearing on being a exspencive gun or a cheap gun the good gun will take a reading at a longer range.now if you want to get more realistic
try a lasar unit alot more precise & exspencive and also can be inaccurate if you direct the beam from coming striaght back or by sending back bougas light flashes back to the recieving unit .all
i'm saying its no way to fool a stop watch if you go from piont a to piont b and it takes a certain amount of time that the speed period no if ands or butts
