摘要
针对红外成像空空导弹的复杂环境适应性评估需求,研究确定了复杂环境的内涵和构成要素。认为复杂环境是种类众多、数量众多的事物及其交互因素构成的难以被导引头分析和理解的场景。定义了因素复杂度和对抗复杂度来量化描述作战环境的复杂程度,提出了建立导引头指标体系的方法,研究了复杂环境指标和导引头指标的体系对应关系。确立了评估导引头复杂环境适应性的概率准则和效率准则,制定了仿真方案和评价指标体系。基于此建立了包括目标干扰模型、背景模型、红外成像导弹模型、仿真结果统计评价等模块的红外成像空空导弹环境适应性仿真评估平台,实现了从靶试条件、仿真结果到劣化指标的快速准确定位,能够评估导引头的环境适应能力,并为其设计改进提供依据。
Focusing on the evaluation requirements of IR Imaging Air-to-Air Missile＇s adaptability to complex environ ment, the concept and compositions of complex environment are established and discussed. The complex environment means the composition of different kinds of things and their interacting factors which are difficult to be analyzed and understood by the IR seeker. Factor complexity and countermeasure complexity are defined to describe the complex environment. The seeker＇s index system is established, and the correlation between complex environment＇s indexes and seeker＇s performance indexes is also researched. Furthermore, the evaluation rules including Probability Rule and Effi ciency Rule are given. Simulation scheme and evaluation index system are also proposed. One simulation and evalua tion platform for IR Imaging Air-to-Air Missile including typical target and decoy module, background module, missile module and simulation evaluation module is established. This platform realizes fast and accurate adaptability evaluation and provides basis to improve the design of IR imaging seeker.
