 The study evaluates the accuracy of Chinese quadpolarization GAFAN-3, GF-3, Synthetic Aperture Radar, SAR, Wave Mode Data for Wave Retrieval and provides guidance for operational applications of GF-3 SAR. The results show that the root mean square error, RMSC, of significant wave height, SWH, is 0.57M using CSAR underscore wave 2, which is less than the RMSC values achieved with other algorithms. However, the retrieval tends to overestimate when SWH is smaller than 2.5M and underestimate with an increasing SWH, indicating room for improvement in the SWH retrieval algorithm using GF-3 SAR acquired in Wave Mode.
