研究了传统旁瓣自适应干扰对消系统,在强近地杂波接收时,由于近地杂波强度太大而影响了对消系统的正常工作,并最终影响到回波有用信号提取这一问题,由此提出了一种基于收敛权值存储的自适应对消系统,并给出了详细实现方案。经理论仿真和实际设备装调,结果证明利用该方案的旁瓣自适应干扰对消系统能有效解决近地接收时强地杂波带来的影响。

The performance of conventional adaptive side-lobe cancellation(ASLC) on radar is studied,and a new ASLC system based on storing convergence coefficients is brought forward.The MATLAB is employed to simulate the behavior of the new presented system and the result shows that the interference can be suppressed via the presented system.Compared with the conventional ASLC system,the presented system in this paper which has been applied in actual furnishment turned out to be with more performance.
