摘要
该文在分析传统顺轨干涉SAR表面流场速度分离方法不足的基础上,根据海面微波成像仿真模型建立了顺轨干涉SAR海洋表面流场迭代反演算法。利用该迭代反演算法对JPL AIRSAR获得的机载顺轨干涉SAR数据进行流场反演,并将反演流场与普林斯顿海洋模型(POM)的输出流场进行对比,两个流场具有很好的一致性,证实了该迭代反演算法的有效性。
In this paper, the shortcomings of traditional methods for wave motions removing are analyzed and an iterative method for ocean surface current retrieval by Along-Track Interferometric SAR （ATI-SAR） based on a microwave ocean imaging simulation model is developed. This iterative model is used to obtain the ocean surface current using the JPL AIRSAR ATI-SAR data. The retrieved surface current is compared with the output of Princeton Ocean Model （POM）. Both surface currents are in good agreement with each other, which proves the effectiveness of this iterative inversion method.
