摘要
针对噪声加密集假目标复合干扰,采取自适应副瓣对消(ASLC)和副瓣匿影(SLB)技术简单级联处理会产生过度匿影问题,提出了一种改进的ASLC和SLB联合抗复合干扰方法.该方法首先将主通道和匿影通道均进行ASLC处理,然后将对消后的数据用于SLB处理.匿影通道经过ASLC处理后压制噪声干扰被抑制掉,确保了后续的SLB处理不会产生过度匿影的问题.仿真结果表明,改进的联合抗复合干扰方法可以达到同时抑制噪声加密集假目标复合干扰的目的.
For the compound jamming of noise encryption and false target, and the excessive blankingproblem resulted from the simple cascade processing of the adaptive sidelobe cancellation (ASLC) and sidelobeblanking (SLB) techniques, an improved method of anti-compound jamming by the combination of the ASLC andSLB is proposed in this paper presents. In this proposed method, firstly, the ALSC processing simultaneously forthe main channel and the blanking channel is performed, then the data after cancellation used for the SLBprocessing, and finally, the blanking channel interference of the suppression noise after the ALSC processing canbe suppressed, which ensures that the SLB processing would not generate the excessive blanking problems.Simulation results show that the improved method of the combined anti-compound jamming can achieve the effectof the simultaneous suppression of the compond jamming with the noise plus the densed false target.
