摘　　要：随着雷达工作的电磁环境越来越复杂,解决雷达与其威力范围内己方电磁辐射设备之间的相容性问题成为研究热点。为了减弱共址MIMO雷达与己方电磁辐射设备之间的相互干扰,以最小化己方电磁辐射设备所占据空频域范围内的雷达谱能量为准则,提出了基于可行点追踪-连续凸逼近的雷达波形与接收滤波器联合优化方法,不仅完成了对雷达谱的塑形,而且实现了对信号依赖性干扰的有效抑制。With the development of the electromagnetic radiation systems involving radars and communication systems,the electromagnetic environment becomes increasingly harsh and the compatibility of the electromagnetic radiation systems has been one of the most popular research hotpots.In order to weaken the mutual interference between the collocated MIMO radar system and its own electromagnetic radiation equipment,a method of jointly optimizing the radar waveform and the receiving filter is proposed through the Feasible Point Pursuit-Successive Convex Approximation(FPP-SCA)algorithm by minimizing the radar spectrum energy in the spatial frequency domain occupied by the own electromagnetic radiation equipment.The proposed method not only shapes the radar spectrum,but also effectively suppresses signal-dependent interference.
