摘　　要：针对密集假目标干扰和单个脉冲干扰组成的复合假目标干扰环境,提出采用基于干扰样本选择的自适应旁瓣相消(JSCJ-ASLC)和副瓣匿影(SLB)联合抗干扰的方法.该方法首先将主通道和匿影通道均进行JSCJ-ASLC处理,抑制掉密集假目标干扰;然后将处理后的数据做SLB处理,抑制掉单个脉冲干扰.同时,为解决匿影天线自适应方向图栅瓣而导致后续SLB处理可能失效的问题,给出了JSCJ-ASLC与分集匿影联合的解决方法.仿真结果表明,该方法可有效实现对密集假目标和单个脉冲干扰的抑制.Aiming at the compound jamming environment of dense false target jamming and single impulsejamming, this paper puts forward a method of combining JSCJ-ASLC and side-lobe blanking （SLB）. Firstly thepaper conducts JSCJ-ASLC processing both for the main channel and the blanking channel to eliminate densefalse target jamming, and then does a SLB processing on the data after being disposed to eliminate single impulsejamming. In addition, in order to solve the problem that the grating lobe of blanking antenna adaptive pattern generatedby extremely large spacing of auxiliary antenna may cause failure of the subsequent SLB processing inpractical engineering, the paper offers an approach of uniting the JSCJ-ASLC with the diversity blanking. Simulationresults show that the proposed method achieves effective suppression for dense false target jamming and singleimpulse jamming.
