Patent ID: 7333049

Claim:
A bistatic radar system comprising: a radar transmitter at a first location on a moving platform having a first motion, said radar transmitter illuminating a target with a first frequency modulated radar pulse and a second frequency modulated radar pulse, said first frequency modulated radar pulse and a second frequency modulated radar pulse transmitted at a pulse repetition frequency, said target reflecting said first frequency modulated radar pulse and said second frequency modulated radar pulse to a receiving antenna having a second motion, said receiving antenna having a difference pattern null; said receiving antenna receiving said first frequency modulated radar pulse and said second frequency modulated radar pulse, reflected from said target to image said target as a main scatterer and an ambiguity of said main scatterer; said first frequency modulated radar pulse modulated starting at a first frequency; said second frequency modulated radar pulse modulated starting at a second frequency; said first frequency and said second frequency chosen to align said main scatterer and said ambiguity of said main scatterer along said difference pattern null of said receiving antenna.
