Patent ID: 7148839

Claim:
A bistatic radar system comprising: a radar transmitter at a first location on a moving platform having a motion, said radar transmitter illuminating a target along an indirect path with an encoded radar signal, said target reflecting said encoded radar signal to a radar receiver, said radar transmitter concurrently illuminating said radar receiver along a direct path with said encoded radar signal, said radar receiver at a second location, said encoded radar signal radiated at a start time from a central reference point, said encoded radar signal containing said first location, said start time, said central reference point and said motion; said radar receiver receiving said encoded radar signal from said radar transmitter along said direct path during a first time interval; said radar receiver receiving said encoded radar signal reflected from said target along said indirect path during a second time interval, said second time interval not overlapping said first time interval; said radar receiver decoding first information contained in said encoded radar signal from said direct path received during said first time interval to extract direct path information; said radar receiver decoding second information contained in said encoded radar signal from said indirect path received during said second time interval to extract indirect path information; said radar receiver combining said direct path information and said indirect path information to phase align said indirect path information to perform coherent bistatic signal processing and compute target data.
