The method of direct solving equations is often applied in the retrieval of lower layer 2-D winds from the dual-Doppler radar data,but there are many limitations:singular points shall pollute their circumambient retrieval results and the observations’ errors would affect the accuracy of retrieval,etc.A variational method in combination with a regularization method is introduced in this paper,wherein a regularization term is added to the target functional and regularization parameters are reasonably selected.Numerical experiments show that the introduction of the regularization term can efficiently filter the errors of retrieval wind field,resulted from singular points and observations,improve the retrieval accuracy,and yield the optimal global retrieval wind field.
