The invention provides a method for determining the optimal resolution of ocean surface wind field inversion based on SAR (Synthetic Aperture Radar), which comprises the steps of acquiring synthetic aperture radar images containing both co-polarization and cross-polarization, and preprocessing the acquired images; performing resampling on co-polarization and cross-polarization backward scattering coefficient images; carrying out ocean surface wind field inversion by using a co-polarization geophysical model function to obtain co-polarized wind field data with different spatial resolutions; carrying out ocean surface wind field inversion by using a cross-polarization ocean model function to obtain cross-polarization wind field data with different spatial resolutions; building a Gaussian model of a root-mean-square error, which changes along with the spatial resolution, of the co-polarization wind field data and the cross-polarization wind field data with different spatial resolutions; and performing first-order derivative derivation on the function, and when the derivative value is greater than -1*10<-4>, regarding the spatial resolution corresponding to the point is the optimal resolution. The wind speed inversed at the spatial resolution is high in accuracy.
