中文摘要：

针对星载微波辐射计反演海洋大气参数的过程,分析了反演通道的选择,比较了线性与非线性反演算法的区别。非线性反演算法逐步舍去低分辨率的低频通道,能够直接有效地提高反演产品的空间分辨率。对几种反演算法的分析和实验表明,非线性反演算法中的基于NelderMead的最优化反演算法相对于线性反演算法,其精度较高,具有一定的开发价值和应用潜力。

英文摘要：

The paper analyzes the channel choice of ocean retrieval algorithm and compares the differences between linear and nonlinear retrieval algorithm by spaceborne microwave radiometer data process.To discard the low-frequency channel in nonlinear retrieval algorithm gradually is a direct and effective way to improve the spatial resolution of retrieval products.Several analyses and experiments for retrieval algorithm indicate that compared with the linear retrieval algorithm,the optimization algorithms based on Nelder-Mead method has higher accuracy,application and development potential.
