摘　　要：提出一种利用模拟目的校核和逼真度验证来评估半实物仿真中红外场景模拟可信度的方法。在探讨模拟目的、逼真度以及"相对等效"原理的基础上,提出特殊的群运算,有效进行了红外场景的模拟目的校核,定性地反映了模拟红外场景达到半实物仿真任务对应模拟目的的能力。将正态分布的思想应用到由偏差度到逼真度的转化过程中,设计算法分别实现了仿真起始点等效逼真度和仿真变化过程逼真度的验证。最后,给出了模拟起始时刻逼真度和变化过程逼真度的权重比较方法,进行了综合逼真度验证,从而定量地评估了模拟红外场景再现实战红外场景的准确程度。An approach to assess the simulation credibility of the infrared scene in the hardware-in-the-loop simulation was proposed,using verification of simulation purpose and validation of fidelity.On the basis of discussing simulation purpose,fidelity and relative equivalence principle,group operation was proposed,and verification of simulation purpose was carried out effectively,which qualitatively reflected whether the simulation IR scene accorded with the simulation purpose of hardware-in-the-loop simulation.Normal distribution was applied in the change from deviation to fidelity,and validation on equivalent fidelity of simulation starting point and changing process fidelity was realized by designing algorithm.At last,the weight comparison between the fidelity of simulation starting point and that of simulation changing process was presented,and validation on the comprehensive fidelity of IR interference simulation was carried out,which quantitatively evaluates the similarity degree between the simulation IR scene and the actual combat IR scene.
