摘要
针对雷达处于强有源干扰环境下目标被淹没的问题,采用一种改进的自适应旁瓣对消设计方法,通过引入辅助天线,将辅助天线接收的信号与主通道接收的信号加权求和,并自适应的调整权值,使输出干扰功率趋于最小,抑制了有源干扰。介绍了改进的自适应旁瓣对消设计方法的原理,确定了辅助天线的位置,并通过仿真验证了改进的自适应旁瓣对消设计方法的有效性。
Aiming at the problem of target submergence in strong active jamming environment,an improved adaptive sidelobe cancellation design method is adopted.By introducing auxiliary antenna,the signal received by auxiliary antenna is weighted sum with the signal received by main channel,and the weight is adjusted adaptively to minimize the output jamming power and suppress active jamming.The principle of the improved adaptive sidelobe cancellation design method is introduced,the position of the auxiliary antenna is determined,and the effectiveness of the improved adaptive sidelobe cancellation design method through simulation is verified.
