摘要

本文对全极化微波散射计遥感海面风场的原理及其特点进行研究，建立了星载全极化微波散射计的系统仿真模型.对比了SeaWinds散射计参数下全极化与同极化的风场反演质量，结果表明全极化微波散射计在星下点以及刈幅远端的区域有良好的风场反演性能，并可提升高风速条件下的风场反演精度.最后分析了极化通道隔离度对全极化散射计系统性能的影响.

Abstract

The principles and characteristics of fully polarized microwave scatterometer was analyzed and a simulation model for fully polarized microwave scatterometer system was established.Wind retrieval quality of fully polarized and co-polarized system were compared under parameters of the SeaWinds scatterometer.The results show that fully polarized scatterometer has better performance than conventional co-polarized system in the nadir region and outlying region in swath.And it can improve wind inversion accuracy under high wind-speed conditions.Finally,the effects of polarization isolation on the measurement performance of fully polarized scatterometer system were analyzed.
