Optimal Waveform Design for Compressive Sensing Radar
摘要
Abstract
To solve the problem of waveform optimization for compressive sensing radar ( CSR ) , an optimized method for CSR waveform design through minimizing the coherence of the sensing matrix is proposed here. The system model of CSR is established and the objective function of the waveform optimization for minimizing the coherence of the sensing matrix is presented. The simulated annealing ( SA) algorithm is employed to find the optimal solution to the objective function taking polyphase coded signal as an example. The optimized waveform can effectively reduce the coherence of the corresponding sensing matrix, and thus improve the accuracy and robustness of the CSR target information extraction. The computer simulation shows that the optimized waveform significantly reduces the coherence of the sensing matrix compared with traditional radar waveforms, and hence confirms the effectiveness of this proposed method.关键词
