摘　　要：介绍了多光谱激光复合点目标运动模拟系统的构成和工作原理。该系统用于光电火控装备及成像导引头系统的研发及验证。3种激光波长(0.65μm、0.808μm、10.6μm)可满足电视(0.4μm～1.1μm)和长波红外成像(8μm～11.5μm)光电跟踪系统的动态仿真测试。12 m半径1/4球幕在0.4μm～12μm宽波段漫反射率大于0.7,点目标运动范围:方位0°～±90°;俯仰0°～90°。该技术已用于车载防空光电火控系统半实物仿真试验评估中,跟踪精度从0.4 mrad提高到0.2 mrad。The layout and operation principle of multi-spectrum laser composite point target simulation dome is given,which is used for research,development and validation of fire control and electro-optical seeker systems.Three laser wavelengths（0.65 μm,0.808 μm and 10.6 μm） meet the dynamic simulation test requirements of TV（0.4 μm～1.1 μm） and long-wavelength infrared imaging（8 μm～11.5 μm） electro-optical tracking system.The diffuse reflectivity of 12m radius dome screen is greater than 0.7（0.4 μm～12 μm）,target motion range is 0 ° ～ ＋ 90 ° in azimuth,and-90 ° ～＋9 0 ° in elevation.This technology is developed for the hardware-in-the-loop simulation of vehicle borne air-defense electro-optical fire control system and the tracking precision is increased from 0.4 mrad to 0.2 mrad.
