摘　　要：根据红外目标设计过程中对红外隐身效果评价的需求,设计开发了基于探测概率的红外目标隐身效果评价仿真软件。使用较为成熟的FLIR92模型,对红外目标设计过程中生成的三维目标热模型数据进行了等效温差处理,再利用二代焦平面热成像系统静态性能模型,仿真了不同系统参数下热成像系统的静态性能,结合探测概率模型估算出不同方向上目标被该红外成像系统发现、定向、识别、认清的距离,从目标探测的角度实现了对不同红外目标设计参数下红外隐身效果的评价。According to the demand for IR target camouflage assessment during the design of IR target, a simulation software based on detection probability was developed. The software used the FLIR92 model which was relatively mature at present to evaluate the thermal imaging system performance, computed the equivalent temperature differential of 3-dimensional IR target model which was generated by IR target design, and then it simulated and computed the imaging system static performance with different system parameters, mainly based on 2nd-focal plane image system static model. At last, on the basis of detection probability, the software estimated the range of detection, direction, recognition and identification of this IR target. It assessed the capability of camouflage of IR target with different system parameters from the perspective of target detection.
