RADAR RETURN FROM VEHICLES IN THE IONOSPHERE.

Abstract

Approximate expressions are derived for radar (backscatter) cross sections of the wakes of vehicles in the ionosphere. Vehicle speed is assumed to be much greater than ion thermal speed but much less than electron thermal speed. It is shown that, under broadside incidence conditions, the large region of mild electron depletion behind the vehicle can give rise to backscatter cross sections approaching 100 square meters. The orientation of the velocity vector with respect to the local geomagnetic field is also shown to be important. (Author)
