摘要
地海面杂波特性对主要采用下视工作方式的机载脉冲多普勒 (PD)雷达具有十分重要的影响 .本文在具体分析PD雷达工作体制的基础上 ,详细研究了载机处于任意飞行姿态下 ,利用三维数字地形高程图和对应地物散射特征分类 ,模拟产生多频段多极化雷达距离 多普勒杂波图的方法 .
The characteristics of the ground and sea clutter have some important effects on the airborne PD radars with look down mode.Based on the analysis of the PD radar system,this paper studies in detail the modeling method of distance doppler clutter graph of the radar by using an elevation graph of 3D digital terrain and the corresponding classification of terrain with arbitrary postures of the aeroplane.Finally,the validity of the method has been proved by the simulation results.
