摘　　要：雷达自适应旁瓣对消技术是抗有源压制式噪声干扰的有效措施之一,对从天线旁瓣进入的高占空比或者连续的干扰信号具有良好的对消效果。针对有源噪声干扰条件下,对雷达自适应旁瓣对消系统的抗干扰性能进行了理论和仿真分析,提出信干噪比增益作为系统抗干扰性能的改进指标,并分别设置不同的干扰条件进行仿真验证,仿真结果表明该指标具有可行性。The adaptive side-lobe cancellation technique of radar is one of the effective measures to confront the active blanket noise jamming,which has good cancellation effect on the high duty cycle or continuous jamming signals coming from the antenna side-lobe.In this paper,the anti-jamming performance of radar adaptive side-lobe cancellation system under active noise jamming condition is analyzed by means of the theory and simulation,the signal-jamming-noise ratio gain is put forward as an improved index of anti-jamming performance of the system,and different jamming conditions are set to verify the simulation.The simulation results show that the index is feasible.
