飞机航路威胁仿真分析

Threat Analysis for Aircraft’s Route Based on Simulation

作战飞机在飞行过程中,会遭遇来自空中、海面或地面的各种威胁,包括雷达对飞机本身的探测及侦察设备对机载雷达的无源侦察,极大威胁到载机的生存。提出了一种仿真分析方法,考虑飞机平台雷达散射面积的各向差异性及机载雷达天线的方向性,将探测或侦察范围中心从传统的计算方转移至作用方,形成“被探测区”或“侦察暴露区”,使指挥员能更客观地判断航路点处的威胁情况,辅助后续筹划,效果已经得到仿真验证。

Operational aircraft may face various threats from air, sea surface or land, including detection of radar to aircraft and passive reconnaissance to airborne radar by detecting equipment, which greatly threats the survival of aircraft. A simulation analytical method is proposed by considering the difference of the plane′s RCS(radar cross section) from each azimuth and the antenna directivity of airborne radar, it shifts the center of detection coverage and reconnaissance range from equipment to action party, forming “detected coverage” and “exposure zone of reconnaissance”, which could help the commander judge the threat at a point of the route more objectively, and provide further assistance in later plan. This method has been proved effective by simulation.
