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
