提出了一种研究半实物仿真中红外目标模拟逼真度的评估方案。红外目标模拟的逼真是整个过程的逼真，将其等价为起始时刻模拟逼真和变化过程模拟逼真的结合。首先对实战场景进行了设置和计算，并分析了逼真度评估指标和评估方法，然后重点研究了起始时刻的等效逼真的评估内容和变化过程逼真的评估内容，最后借助权重计算，将起始时刻等效逼真和变化过程逼真结合起来得到了红外目标模拟的整体逼真度。

An evaluation scheme for studying the fidelity of IR target simulation in the hardware-in-the-loop simulation is proposed. The verisimilitude of IR target simulation can be equal to an integration of the simulation verisimilitude of the starting point and the change process. Firstly the warfare scene is set and calculated, and the evaluation index and method are analyzed. Then, the content of the equivalent verisimilitude of the starting point and the change process is studied with emphasis. At last, based on the weight calculation, the whole fidelity of the IR target simulation is obtained by combing the starting point equivalent verisimilitude and the change process verisimilitude.
