基于松弛交替投影的MIMO雷达相位编码波形设计
Phase-Coded Waveform Design via ReIaxed AIternating Projection for MIMO Radar
摘要
Abstract
The sophisticated scenarios always challenge MIMO(Mutiple-Input Mlitiple-Output)radar.A relaxed iter-ative spectrum approximation alternating projection method (RISAAP)is proposed to design phase-coded waveforms,for suppressing high range sidelobes of strong scatters,electromagnetic interference in specified frequencies and cross-interfer-ence from different signals.This method is based on power spectral density (PSD)approximation and alternating projection with extended accelerating factor.Firstly,the correlation fitting is transformed into PSD approximation via FFT between the aperiodic correlation function and PSD.Secondly,the desired spectrum constraint is formulated and the projection space is expanded by its relaxed mechanism.Finally,the iterative optimization is conducted via FFT and accelerated alternating pro-jection.Simulations demonstrate that this method could obtain efficient performance and avoid local stagnation which seems more convenient for waveform design on-the-fly than some prevalent algorithms.关键词
