摘要
针对低空目标突袭的威胁,根据低空目标普遍携带雷达高度表的特征,提出了基于雷达高度表信号探测的低空目标检测技术。针对海面飞行环境,根据双基地雷达的原理,对海面雷达散射信号进行了理论计算,从功率角度对低空目标检测可行性进行了分析,并给出了将侦察系统升空探测低空目标所携雷达高度表信号的方法,达到了对低空突防目标预警探测的要求。
A Low altitude target detection technique based on signal detection of radar altimeter is proposed to resolve the problem of low altitude target attack,as low altitude targets widely take radar altimeter. The method of heightening reconnaissance system to detect radar altimeter signal of low altitude target is proposed in environment of sea surface,which can satisfy the desire of warning detect of low altitude targets.
