摘要
海浪传播方向180°不确定性是海浪遥感的固有问题。根据海浪传播理论,提出了解决该问题的一种新方法。利用该方法可直接由合成孔径雷达(SAR)图像确定海浪的传播方向,消除波向180°不确定性。实例研究表明,利用该方法确定海浪传播方向与同步海浪数据有很好的一致性。
Synthetic aperture radar(SAR)is an instataneous imaging system which gives a snaoshot of the sea surface.There exists a 180°propagation direction ambiguity prblem when ocean waves are imaged by a SAR.Complex SAR imagery must be used to resolve the problem in addition to in situ measurements at present.A new method is developed based on the propagation theory of gravty waces in this paper.By using this method,only a single frame of real SAR image is needed.The processing procedure is simple and especially suitable for operational use.The results from a case study show good agreement with in situ measurements.
