声诱饵对尺度目标的回波模拟方法
Decoys simulating scale highlights

潜艇回波可以等效成若干个散射亮点回波相干迭加的结果,现代声自导鱼雷基于这一物理事实,通过辨识目标尺度来识别真假目标。提出使用具备数据通信能力的多个点源声诱饵,通过信息交互实现各声诱饵回波发射延时的有序控制,实现对尺度目标的多亮点回波模拟。具体仿真算例表明,该方法对利用方位走向特征和声成像进行目标尺度识别的鱼雷具有对抗效果。
The structural highlight echo returned from a submarine is a very remarkable feature for a torpedo on attacking to identify true target. Developing assembled decoys which are distributed randomly in space but coordinated by underwater communication is valuable for imitating the structural highlight spots of echo sound in order to counteract the torpedo. The approaches of coordinated schemes, such as delays between spots in term of arrivals of the torpedo, is proposed and verified feasible by mathematical simulation.
