一种基于地形匹配的雷达模拟器地杂波 回波的设计与实现

Design and Implementation of a Terrain-matched Ground ClutterSimulation Method for Radar Simulators

在现有的雷达模拟器中,模拟地杂波时没有使用地形信息,起不到逼真地描述雷达工作状态的作用。本文把杂波区划分成各小单元,结合地形高度数据计算各杂波单元的散射面积,并使用相干视频回波模型实现了地杂波回波模拟,最后在某型号雷达模拟器中给出了地杂波回波的实现结果,验证了该方法的可行性,实现了与地形匹配的地杂波回波模拟。

Current radar simulators do not use terrain information when simulating ground clutter,so that the working conditions of the radar cannot be described realistically.In this paper,the clutter area is divided into multiple small units,and the scattering areas of each unit are calculated with the terrain height data being employed.The ground clutter simulation is realized by using the coherent video echo model.Finally,the proposed ground clutter simulation method is implemented in a radar simulator.The implementation results show terrain-matched ground clutter simulation,which proves the feasibility of the proposed simulation method.
