摘要: 对GPS反射信号的功率波形以及GPS信号在海面的散射区域进行了阐述,并对海面风场反演的原理和方法作了具体的介绍。处理了NASA在Michael飓风中机载实验的数据,反演得到的风速精度为2 m/s左右,从而验证了通过GPS反射信号反演海面风场在理论和实践上的可行性。Abstract: The propagating geometry and the waveform of the GPS reflected signals were expatiated in detail.Furthermore,the principle and the method of retrieving ocean surface wind were presented.In order to test the feasibility of retrieving,the experiment data obtained by NASA in hurricane Michael was used.The result shows that the estimated retrieval accuracy of wind speed is about 2 m/s.
