摘要
针对机载IRST系统理论探测与实际探测能力之间的较大差异及其作战能力发挥不充分等问题, 首先分析了机载IRST最佳工作点与作战需求和探测能力之间的关系, 然后考虑了目标机相对载机进入角、方位角、俯仰角和环境背景辐射等作战因素, 建立了机载IRST角水平和角俯仰探测能力模型, 最后综合作战环境和探测概率特性提出探测概率包线概念, 建立了机载IRST作用距离探测概率包线模型, 并定量分析了不同空战态势中机载IRST的探测能力及其概率。从仿真结果可以看出, 当满足一定的虚警概率和信噪比要求时, 探测概率包线的分布特性具有最佳探测点, 这为引导战机扭转战场态势, 充分发挥机载IRST作战效能提供了理论参考, 也为模拟真实战场环境和在实验室进行试验提供了一定的理论支撑。
Abstract
According to the difference between theory detection and battlefield detection ability of airborne IRST system, the relation between airborne IRST and operational requirement or detection ability was analyzed firstly. Secondly, considering the operational factors as relative entering angle, azimuth angle, pitch angle, environmental background radiation and so on, the models of detection ability in level and pitching angle on airborne IRST were built. Finally, the concept of detection probability envelope was put forward based on operational environment and the character of detection probability, and the model of detection probability envelope on operating range and the ability of airborne IRST and its probability were analyzed quantificationaly in different battlefield situations. It can be seen from the results of simulation that when meeting the demands of false alarm probability and SNR, the detection probability envelope has optimum detection point, which provides theoretical reference for guiding aircraft to change the situation and develop the operational effectiveness of airborne IRST. Meanwhile, it also provides theoretical support for simulating real battlefield environment and test in lab.
