中文摘要：

经典的海洋表面流场迭代反演算法采用固定的校正系数对探测区域进行整体分析和计算,因此耗时较长且反演精度也受到了一定程度的限制。本文提出利用模拟退火算法对反演过程中的校正系数进行优化,使其能根据每一次反演的结果进行自适应的调整和改变,从而减少迭代次数;同时根据流场分布的特点,提出划分探测区域的反演方法,最终,在经典算法的基础上给出了改进的海表流场反演算法。仿真反演实验结果表明,改进后的反演算法,其时效性和精度都有了明显提高。

英文摘要：

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, detec- tion 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 effi- ciency and accuracy of the improved inversion algorithm are obviously improved.
