| 摘 要： | 针对集中式相参MIMO雷达的抗干扰能力进行了研究。分析了MIMO雷达的抗侦察截获、抗信号分选以及抗副瓣干扰能力，同时对比了传统相控阵雷达的抗干扰能力。基于雷达截获方程，对比了MIMO雷达与传统相控阵雷达主瓣/副瓣的抗侦察截获能力。分析了MIMO雷达发射正交波形合成信号的时空伪随机特性。对比了不同阵列构型的MIMO雷达对抗不同类型的副瓣干扰的能力。利用理论公式推导和仿真试验，验证了上述结论的正确性。

| Abstract: | The anti-active jamming performance of centralized coherent MIMO radar is studied. The MIMO radar signal interception range, the effect of received signal sorting capability of jammer and the anti-active sidelobe jamming capability is considered. Based on the radar interception function, the interception range of MIMO radar and the mainlobe and sidelobe of phased array radar is compared. The space-time pseudorandom characteristics of synthesized signal which is combed by MIMO radar transmitted multiple orthogonal signals is discussed. The capability of suppression different type sidelobe jamming of different array structures of MIMO radar is analyzed。Theoretical formula derivation and simulation result is given to prove the analysis. |
