Patent ID: 8860605

Claim:
A method for estimating a position and speed of a target using a radar, the radar emitting a waveform comprising a train of M pulses, where M≧2, each pulse comprising an Orthogonal Frequency Division Multiplexing chip constructed from N sc subcarriers, where N sc ≧2, the subcarriers covering an entirety of the bandwidth of the radar, the method comprising, upon receipt of echoed pulses by the radar: among the N sc subcarriers, Doppler processing N dopp subcarriers using at least one processor, where N dopp <N sc , each of said N dopp subcarriers being fixed over the M pulses; and among N sc −N dopp subcarriers that are not used for Doppler processing, High Range Resolution processing N HRR subcarriers using at least one processor, where N HRR ≦N sc −N dopp , said N HRR subcarriers being randomly distributed over the M pulses.
