摘要
目前反辐射无人机已成为防空武器的重要作战目标。利用被动声探测系统来探测反辐射无人机是一种新的方法,通过对线列和圆弧阵结构的声探测系统基阵进行计算和仿真,针对阵列指向性受影响的因素,对基阵的各种参数进行了优化设计。分析结果表明半圆柱型基阵在波瓣宽度和增益上满足系统对无人机的探测要求。
Presently, anti-radiation UAV has become the important aim of the aerial defence weapon. The passive acoustics detection system is a new way for detecting the anti-radiation UAV. By means of the calculation and simulation of the linear and circular array, aimed at the factors which influence the directivity of the array,several parameters are analyzed and selected for optimal design. As a result, the beam width and gain of the half cylinder array are enough for the system to detect the UAV.
