An infrared radiant augmentation technique for target drones

为了在外场试验中检验红外制导武器系统的工作性能,需要使用靶机红外增强装置实现对真实目标红外辐射特性的模拟。介绍了一种利用光学方法实现靶机红外辐射增强和目标辐射特性模拟的技术。使用高亮度红外光源作辐射源,通过对光学系统的控制,在实现红外辐射增强的同时,可模拟不同距离和方向的红外辐射强度特性。通过建模对所模拟目标的红外辐射强度及辐射方向特性进行了分析,并以此为设计依据设计了光学系统。实现了对最大红外辐射强度为1600W/sr的目标辐射方向特性的模拟。

In order to test the performance of IR guidance weapon systems in the outfield experiment,it is necessary to load an IR augmentation device on target drone to simulate the IR characteristics of a real target plane.The commonly used IR augmentation has low IR radiation intensity and can not reflect the direction dependent radiation properties.An IR augmentation technique based on optic method is introduced.A high brightness IR light source is used to generate IR radiation.The radiation intensity is controlled according to the missile target-plane distance and direction,which are detected by an optoelectric tracing system.Based on the simulation results of the radiation intensities with different distances and radiation angles,an optical system is designed.The experimental results indicate that the IR radiation characteristics of a target with a maximal radiation intensity of 1600W/sr is simulated by using the technique.
