Modeling and Simulation of Infrared Imaging Seeker for Air-to-Air Missiles

红外成像导引头仿真平台是分析导引头性能的重要手段,通过分析红外成像导引头仿真系统的设计要求,建立了仿真系统的总体结构,主要包括红外图像合成系统、成像探测系统、图像处理系统和平台伺服控制系统,并描述了各子系统的功能、组成、模型原理和工作过程。它们模拟了导引头接收目标红外辐射、从背景和干扰中检测识别目标并进行跟踪的过程。给出了系统的实现途径和攻击仿真实例,验证了系统的有效性,表明系统可用于改进导引头的性能设计。

The simulation environment for infrared imaging seeker is one important tool to analyze the seeker＇s performance.By analyzing the simulation system＇s design requests, its whole architecture was brought out, including infrared image generation system, imaging and detecting system, image processing system and platform servo control system, and also the subsystems ＇function, form, theory and working process were described. They simulated seeker to accept infrared radiation, detect and recognize targets, and track target from background and countermeasures. The implementing approach and an airborne simulation case were proposed, which validated the simulation system and indicated it could be used for improving seekers＇ performance design.
