Spectrum analysis of multiple PRF radars based on the compressive sensing method

In this paper, an algorithm for spectrum analysis of multiple pulse repetition frequency (PRF) radars is presented. The algorithm is based on the compressive sensing theorem and uses the sparsity characteristic of received signal in frequency domain and universal sampling pattern of multiple PRF pulses for determining the Doppler frequencies of targets. The algorithm works properly in lower sampling rates and in the presence of multiple targets and ground clutter. Simulation results are presented for evaluating the performance of the algorithm.
