:文中提出一种能使机载红外搜索跟踪系统 (IRSTS)在单站单波段条件下实现被动动态测距测速的技术方案。该方案融合了红外探测器对目标辐射的响应信息 ,利用机载惯性导航系统(INS)提供的本机状态参数 ,建立了动态获取目标距离和速度信息的解算模型———SSIR VRM模型。大量的仿真研究证明了该模型的可行性 ,其测量精度基本能满足机载导弹火控解算的需要。

A technical scheme, which is planned for airborne infrared searching and tracking system (IRSTS) to make it perform the function of dynamically measuring the range and velocity of targets, is developed in this paper. In this scheme, the outputs of infrared sensors and the information of airborne inertial navigation system (INS) are used to set up a model called SSIR\|VRM, which can dynamically calculate the range and velocity of target aircraft on single waveband with only single platform. Numerous experiment have been taken to illustrate the feasibility of SSIR\|VRM, and the results are promising.
