摘要 自适应旁瓣对消(ASLC)技术是现代雷达抗干扰的有效方法,它通过辅助通道在干扰方向自适应形成零点以实现对干扰的抑制,在雷达上得到了广泛的应用。对雷达自适应旁瓣对消抗梳状谱干扰进行了仿真。首先从雷达自适应旁瓣对消的数学模型出发,推导建立了自适应旁瓣对消的最优权矢量,在此基础上建立了梳状谱干扰的理论模型,并对ASLC对抗梳状谱干扰的性能进行了数值仿真。该研究对于提高现代雷达抗干扰能力具有一定的参考意义。 Adaptive sidelobe cancellation(ASLC)technology is an effective anti-jamming method for modern radars,and it can suppress jamming by forming zero adaptively in the jamming direc-tion by using auxiliary channels,so is widely used in radars.In this paper,the radar ASLC against comb spectrum jamming is simulated.First,the optimal weight vector of adaptive sidelobe cancel-lation is derived and established from the mathematical model of radar ASLC.On this basis,the theoretical model of comb spectrum jamming is established,and the performance of ASLC against comb spectrum jamming is numerically simulated.The research has certain reference significance for improving the anti-jamming capability of modern radar.
