Research on Simulation of the Airborne Infrared Search and Track System based on Hiberarchy

从机载红外搜索跟踪系统(IRST)的组成原理和功能分析出发,采用层次化构架体系建立了机载红外搜索跟踪系统的功能仿真模型。在此模型中,提出了在信息源联网条件下状态优化的方法,研究了机载红外搜索跟踪系统的状态推进模块。使用"网格法"分析了机载红外搜索跟踪系统扫描模拟模块。通过对最小可检测辐射强度的求解,分析了机载红外搜索跟踪系统的目标探测模块。基于上述模型进行了仿真研究,仿真结果表明了该模型的合理性和有效性。

Through analyzing the structure and function of airborne Infrared Search and Track System（IRST）,a functional simulation model of the Airborne IRST was established based on hiberarchy.In this model,a state optimization method,which can be used in condition of information source interconnection,was presented and the IRST states operation process was researched.The scan process of the IRST was analyzed with Grid Method.The Target Detection process for the IRST system was analyzed though studying the minimum detectable radiant intensity.Experimental result shows the models＇ rationality and validity.
