A Scene Simulation Based on Vega for Low Altitude Infrared Warning System

介绍了红外仿真的基本流程,并且基于Vega建立了低空红外预警仿真系统。针对低空红外预警的复杂场景,分别建立了目标和背景的辐射模型;考虑大气对红外辐射的衰减作用,建立了大气的传输模型;根据探测器的成像特性建立了成像系统响应模型。最后给出了仿真流程和仿真结果,并将仿真结果应用到实际预警处理系统中。

Based on the basic procedure of infrared imaging, the pure computer simulation system for low altitude infrared warning system is established. The target and background physical model and infrared radiation are constructed and calculated separatedly based on Vega. Then the attenuate factor of atmosphere between scene and infrared sensor was calculated from atmosphere attenuate model. The infrared imaging system is simulated for generating the final infrared image. Last, the simulation procedure is given, and the image sequence is used in actual infrared warning system.
