不同航迹雷达回波强度分析

针对空情复杂多个目标容易混批的问题,在对雷达回波强度分析的基础上,结合实际的雷达程式,对某高度波束平面和三条不同航迹时的雷达回波强度进行计算分析,仿真结果表明:雷达回波强度在波束平面内会有不同的变化,在波束中心时最大;目标沿三条不同航迹飞行时回波强度的分布近似为抛物形、鞍形和双抛物形。此方法亦可用于对不同高度航线的分析。

The Analysis of Radar Echo Intensity in Different Flight Path

Aimed at the problem that many targets are easily mixed in complex air condition,based on the analysis of radar echo intensity,combined with the actual radar mode,this paper canculates and analyzes the radar echo intensity in the beam plane and three different flight paths at a certain height,simulation results show that radar echo intensity vary and reach maximum in the center of wavebeam,the distribution of radar echo intensity are approximately parabola,saddleback and double-parabola in three different flight paths.The simulation method is also of value for the analysis of different height airline.
