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（0.65 m、0.808 m、10.6 m）可满足电视（0.4 m～1.1 m）和长波红外成像（8 m～11.5 m）光电跟踪系统的动态仿真测试。12 m半径1/4球幕在0.4 m～12 m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。Abstract: 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 m, 0.808 m and 10.6 m) meet the dynamic simulation test requirements of TV (0.4 m～1.1 m) and long-wavelength infrared imaging (8 m～11.5 m) electro-optical tracking system. The diffuse reflectivity of 12m radius dome screen is greater than 0.7 (0.4 m～12 m), 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.
