摘要

针对传统反狙击探测方法主动性差、定位精度低的不足,提出了一种运用“猫眼效应”原理实现激光主动探测的反狙击方法。系统采用半导体激光器作为光源,以线阵CCD作为激光回波探测器。光学系统将一定角度的接收视场和线阵CCD的2160个像元位置相对应,探测精度可达mrad量级。CCD工作时序由FPGA产生,其程序可在线编译。结合帧减和阈值比较算法,最大程度上剔除了噪声,试验探测距离可达250m。

Abstract

To improve the detection performance and location finding accuracy of the conventional sniper detection, an active laser detecting method was designed based on cat eye effect theory. The device takes a semiconductor laser as light source and a linear array CCD as laser echo detector. The specific reception field of view was matched with 2160 elements of linear CCD by using proper optics system, and its detection accuracy reached the level of mrad. Operation timer of CCD was created by FPGA and the program could be compiled on line and modified conveniently, which could improve the speed of design greatly. The system is simple and portable, and it has its own power management system. The detection distance reaches 250 meter after minimizing noise by frame-subtract and threshold comparing algorithm.
