摘　　要：针对方位和多普勒信息均不确定条件下集中式MIMO雷达的稳健目标检测问题,基于最大化最差输出信干噪比(SINR)的波形设计准则,利用半定规划(SDP)优化来交替优化发射波形和接收滤波器.为进一步提升检测性能,采用脉内和脉间联合设计波形.最后分析了波形的峰均比约束对输出SINR性能的影响.仿真结果表明,与单纯脉内和单纯脉间波形相比,联合波形具有更加鲁棒的输出SINR性能.Aiming at robust target detection of co-located MIMO radar under uncertain azimuth and Doppler information, and based on the waveform design criterion of maximizing the worst output signal-to-interfer-enceand-noise-rate (SINR), this paper uses semi-definite program (SDP) optimization to alternately solve the transmitted waveform and the receiving filter, then adopts intrapulse and interpulse combined waveform to further improve the detection performance, and finally analyzes the influence of waveform’s peak-to-average ratio (PAR) constraint on output SINR performance. Simulation results show that compared with pure intrapulse waveform and pure interpulse waveform, the combined waveform has more robust output SINR performance.
