摘要
由于缺乏散射计的σ°资料及相应的海面风数据，本文采用数值模拟方法对反演算法及多解消除步骤进行了初步的研究。结果表明，对于NSCAT散射计的设计参数，采用常用的反演算法进行模拟，约有70％的第一解是真实解。经过平滑处理之后约有95％反演解达到了散射计的设计精度，即风速误差＜2m／s或10％（取大者），风向误差＜20°。
Due to the lack of the σ° data from satellite wind scatterometer and associated in situ data of ocean surface winds we have devised a numerical simulation program to do some preliminary studies on the wind retrieval algrithms and ambiguity remval steps. Primary results indicate that the cmmonly used algrithms work well for the NSCAT configuratin adopted in our simulation and more than 70% of the rank 1 solutions are selected as the final solution. After our smoothing processing nearly 95% of the final solutions reach the scatterometer specifications with speed deviation less that ±2m/s or 10% (the larger ne) and directional deviatin less than ±20°.
