研究了一种红外场景/点源目标模拟器。模拟器由一路红外场景、一路点源目标和四路点源干扰组成。模拟器包括点源目标/干扰通道、中继光学系统、成像通道、多目标复合系统、运动控制系统和机械支撑及连接结构,可以同时模拟一路点源目标,四路点源干扰和一路红外场景。对模拟器进行实验研究,模拟器所生成红外图像的空间分辨率达到10 lp/mm,模拟器点源光斑尺寸最小为42μm,最大为499μm。该模拟器已经成功应用到半实物仿真试验中。
An infrared scene / point source simulator is studied. The simulator consists of one infrared scene, one source point and four point source interference. The simulator includes point source / disturbance channel, relay optical system, imaging channel, multi-target complex system, motion control system and mechanical support and connection structure. Simulator can simultaneously simulate the source point of all the way, four-point source interference and one infrared scene . The experimental study of the simulator, the spatial resolution of the infrared image generated by the simulator reached 10 lp / mm, simulator point source spot size of a minimum of 42μm, a maximum of 499μm. The simulator has been successfully applied to the semi-physical simulation test.
