The classical ocean surface current iterative inversion algorithm used constant correction factor to analyze and calculate the whole detection area, so it is time-consuming and the accuracy is limited. In order to improve the efficiency and accuracy of the inversion calculation, this paper used simulated annealing algorithm to optimize the correction coefficient, which can be adaptively changed according to the result of each inversion. Moreover, detection region was divided according to the characteristics of the current distribution. Finally, a modified ocean surface current inversion algorithm is proposed based on the classical method. The simulation results show that the efficiency and accuracy of the improved inversion algorithm are obviously improved.
