摘要
基于先进的矢量网络分析仪，组建了一套用于地物后向散射特性测量的多波段（2－18GHZ）全极化散射计系统，本文对系统的硬件组成及软件设计给出了详细的介绍和分析，并根据绝对校准实验和实际测试结果对该系统的性能予以讨论。综合分析表明，利用矢量网络分析仪的时域门功能，合理选择设置参数，可实现地物散射系数的精确测量。
Based on advanced vector network analyzer HP8720C, one multifrequency polarimetric scatterometer system has been made up which is used to measure back scattering proghies of terrain.This paper introduces and analyzes the hardware and software design of the system and discusses the system properties based on results of the absolute calibration and real measurement. It is shown that accurate measurement for terrain scatter coefficient can be achieved by using function of time domain gating with appropriate parameters.
