一种机载红外搜索跟踪系统多目标跟踪精度测试系统设计

摘要

Multi-target tracking accuracy is an important indicator of airborne Infrared Search and Track (IRST) system,and the experimental verification of it under test flight conditions is not only costly but also difficult.Based on the features of multi-target tracking of IRST system,a semi-physical simulation system was designed for multi-target tracking accuracy testing.The system consists of a target simulation system,a dynamic excitation system,a system controller,a data acquisition processor and other components.By connecting to a transmission network composed of high-speed Ethernet and avionics busses,it can carry out dynamic testing of multi-target tracking accuracy under laboratory conditions.This paper describes the system composition,function and detailed design of the key target simulator,and the working principle of the multi-target tracking accuracy testing is also given.%多目标跟踪精度是机载红外搜索跟踪系统的重要指标,在试飞条件下进行测试验证不但试验费用高而且难度大.针对红外搜索跟踪系统多目标跟踪的特点,设计用于多目标跟踪精度测试的半实物仿真试验系统,该系统由目标模拟系统、动态激励系统、系统控制器和数据采集处理器等组成,通过与由高速以太网和航电总线组成的传输网络的连接,可在实验室条件下开展多目标跟踪精度的动态测试.介绍了测试系统的组成、功能及关键目标模拟器的详细设计,并描述了利用该系统进行多目标跟踪精度测试的工作原理.
