摘　　要：为了探测敌方激光的来袭方向,开发了一种激光脉冲方向告警系统。该系统由光学模块、信号处理模块和显示模块组成,其探测范围为水平方向0°～360°,垂直方向0°～90°,角度分辨率30°,识别出波长为0.85,1.06和1.54μm,脉宽不小于10 ns的激光脉冲,探测功率密度下限为1 mW/cm2,其探测概率达到98%以上,并可实时报警。与同类装置比较,该系统角度分辨率进一步提高,探测功率下限满足了实际探测距离为5～10 km的探测需求。For detecting laser attacking direction from enemy,we develop a warning system which can detect the direction of coming laser pulse.This system is composed of optical module,signal processing module,and display module.Its detection range is 0° to 360° on the horizontal direction and 0° to 90° on the vertical direction,and angle identification is 30°.Laser pulse wavelength of 0.85,1.06 and 1.54 μm,pulse width no less than 10 ns,can be distinguished.The floor of detection power is 1 mW/cm2,the detection probability is more than 98 percent,and it realizes real-time warning.Compared with former devices,its angle identification is developed,and the floor of detection power is 5～10 km and meets the need of detected.
