Patent ID: 8565687

Claim:
A method for detection of a signal of interest in signal samples collected by a single antenna mounted on a moving platform, wherein the signal samples comprise signals having fixed patterns that are repeated over a fixed repetition rate F fr , the method comprising: collecting by the single antenna a first signal sample from the moving platform at time T 1 , wherein the platform moves at a rate of V meters per second; collecting by the single antenna a second signal sample from the moving platform at time T 2 , wherein T 2 −T 1 =1/F fr ; treating the first signal sample as received by a first antenna mounted on the moving platform and treating the second signal sample as received by a second antenna mounted on the moving platform, wherein the first and second antennas are separated by a distance of V/(1/F fr ); and processing by a receiver the first and second signal samples to detect the signal of interest.
