摘要/Abstract

摘要： 雷达极化信息处理的基础是极化测量,目前现有的目标全极化散射矩阵是通过正交双极化通道分时测量体制或瞬时测量体制得到的,对极化测量信号要求高,测量精度比较高,但系统复杂程度和代价也相对较大。利用单板化天线的空域极化特性对雷达接受回波信号进行处理,无需对雷达进行结构改造而仅进行软件技术更新的情况,也能够获得目标的全极化散射矩阵。将从理论分析和计算机仿真实验2个方面对这2种极化测量体制进行比较和性能分析,通过仿真验证厂新方法的优越性和广阔的研究前景,但也存在一定局限性。

Abstract: The basic theory of radar polarization signal processing is measurement of the target scattering matrix. The current algorithm of measurement of the target scattering matrix is gotten through orthogonal dual polarization channel in time-sharing or simultaneously, which demands orthogonal polarization measurement signals with complex coding. The measuring accuracy is higher. The complexity and the cost of the system are relatively higher. Scattering matrix can also be obtained by making use of the spatial polarization characteristics of the antenna to processing the radar echo without structure reformation of the radar. It only. needs to renewal measurement technology. The comparison and performance analysis between the measurement method existed are given by theoretical analysis and simulation experiment. The superiority of the new method is verified which has broad prospects of research & application, although it has some limitation.

Key words: target scattering matrix, polarization, instantaneous measurement, spatial polarization characteristic
