 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（0.65 μm、0.808 μm、10.6 μm）可满足电视（0.4 μm～1.1 μm）和长波红外成像（8 μm～11.5 μm）光电跟踪系统的动态仿真测试。12 m半径1/4球幕在0.4 μm～12 μm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。

Simulation of multi-wavelength laser composite point target motion

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.
