机载预警雷达探测空间动态性能分析

Analysis of Dynamic Performance of AEW Radar Detecting Area

机载预警雷达的动态探测性能尚无统一的度量标准。该文针对双平行线的一般情况,采用相对运动的方法,以目标进入雷达探测区的概率为指标,对影响机载预警雷达探测空间的三个主要因素———载机-敌机速度比、平行线长度-探测半径比和平行线间隔-探测半径比,给出定性和定量的分析,运用蒙特卡洛法仿真计算,并得到更一般的结论:在满足作战需要的前提下,对于均匀分布的匀速目标,应增大载机速度,减小巡逻边长与探测半径之比,以提高机载预警雷达探测空间动态效能。对于目标非均匀分布,以及载机采用其它巡逻航线的情形,本文所给方法同样适用。

There is no uniform measure for dynamic performance of AEW radar detecting area yet. Aiming at the normal situation of symmetric linear patrol, this paper gives qualitative and quantitative analysis on main factors of AEW radar detecting area, which are, carrier - enemy velocity ratio, symmetric line length - detecting range ratio, and symmetric line distance - detecting range ratio, with measure of the enter - cover - probability. Monte - Cario Method is used for simulation and computation. This paper achieves more general conclusions ： the carrier velocity should be increased and the patrol line length - detecting range ratio should be decreased to improve the dynamic performance. Methods given in this paper are also applicable in other situations.
