摘　　要：为解决全向凝视红外多目标跟踪系统室内调试时无合作目标配合实验难题,提出一种红外多目标半实物仿真系统。该系统由多个可控热源组成,每个热源包括均匀加热的平板和温控装置。改变光栏大小和温度分布,模拟不同距离、不同大小的目标。热源安装在三维运动的载体上,以不同速度、方向运动可模拟不同目标的运动轨迹。对3个红外模拟目标600帧图像的采集和处理,实现了航迹重迭、交叉和分离的全过程仿真,验证了本实验平台的模拟精度。An infrared multi-target hardware-in-the-loop simulation system is proposed to provide cooperative targets during lab debugging for a panoramic multi-target tracking infrared staring system.The system consists of several controllable heat sources,each of which is installed on a three-dimensional moving table and incorporates a uniformly-heated plate and a temperature controller.Targets in different distances and different sizes were simulated by changing the diaphragm aperture and the temperature distribution,while different target tracks were simulated with heat sources at different velocities and directions.Finally,600 frames of three infrared simulated targets were acquired and processed,and the whole process of track overlapping,intersection and detachment was simulated,which demonstrated the feasibility and accuracy of this experimental platform.
