摘要:

充分考虑海浪成长状态,根据四层介质模型和入射—反射波理论,对Zhao等提出的风速反演算法进行了改进。此改进算法和Zhao等提出的解析反演算法相比,风速反演结果较接近一些经验算法,如Brown算法、Young算法等。该算法在一定程度上弥补了解析模式未考虑具体海况实践的不足,又克服了经验模式函数的一些局限性。其不仅适用于低风速反演,而且适用于高风速反演,并且能取得更好的风速反演精度和效果。

Abstract:

Being considered about the effect of wave states on the wind speed retrieval,in this paper an improved analytical algorithm was proposed based on a four-layer dielectric model and the incident-reflected wave theory.Compared with the analytical algorithms proposed by Zhao et al,this improved algorithm was in a better accord with some empirical algorithms such as Brown algorithm,Young model function and et al.The new analytical algorithm to some extent not only made up for some shortcomings that did not consider sea states in specific practice for analytical model functions,but also overcome some limitations of empirical model functions.This new algorithm would be suitable not only for low wind speed inversion,but also for high wind speed retrieval.Better accuracy and effectiveness of wind speed retrieval can also be obtained.

Key words: Satellite Altimeter    Wind speed retrieving algorithm    Wave state    Analytical algorithm    Whitecap coverage rate
