Velocity ambiguity resolving for moving target indication by compressed sensing

A novel velocity ambiguity resolving method is proposed for moving target indication, in which compressed sensing (CS) is applied to recover the unambiguous Doppler spectrum of targets from randomly pulse repetition frequency-jittering pulses. Weighting in CS recovery is utilised to suppress the clutter by using prior knowledge of the clutter spectrum. Experimental results demonstrate the effectiveness of the proposal.
