Abstract

Quadrature Compressive Sampling radar is a newly introduced radar for pulse Doppler processing with sub-Nyquist samples. This paper considers diverse transmitting pulses and proposes a scheme to perform the estimation of targets in the presence of a repeat jammer. The scheme first performs whitening processing on sub-Nyquist samples to suppress repeat jammers, and then with the principle of orthogonal matching pursuit, it estimates the targets by iteratively performing matched filter and discrete Fourier transform on sub-Nyquist samples in a coherent processing interval. The theoretical analyses conducted on the capability of rejecting the repeat jammers, reveal that the signal to interference plus noise ratio, after whitening processing, almost approaches to the input signal to noise ratio and is not affected by the strength of the repeat jammers. The simulation results further validate the effectiveness of the proposed scheme.
