摘要

在高频区（光学区），雷达目标回波可模型化为多个散射中心回波的合成，隐含着目标精密的几何形状信息；宽带高频雷达可以获得目标多散射中心在径向距离轴上的投影分布，即目标的一维距离像；对距离像上孤立的每个强散射中心进行极化描述，可获得其对应的单元散射体的几何结构特性；由多个单元散射体可构造出目标的结构图像，即距离──极化结构图像，文中主要给出了强杂波背景下目标结构成像的原理、方法及其计算机仿真结果。

Abstract

At high frequencies

radar target can be described as returns from multiple scattering centers and the returns reveal precision geometric shape information of target.With a modest bandwidth of transmitted signal

the spacial distribution along radar radial range axis which is called range profile can be obtained from received signal.By polarization data processing of each scattering center isolated on range axis

the geometric shape and structure of the scattering center can be obtained.And the range-polarization reconstructure is obtained from multiple scattering centers.This paper studies the theory of target rangeploarization reconstucting and presents a novel method of obtaining R-P reconstructure under strong land clutter background.The results are shown by computer simulation.
