%X Synthetic aperture radar(SAR)is an instantaneous imaging systemwhich gives a snapshot of the sea surface. There exists a 180°propagation direction ambiguity problemwhen oceanwaves are imaged by a SAR.Complex SAR ima- gery mustbe used to resolve the problem in addition toin situmeasurements at present.Anewmethod is developed based on the propagation theory of gravitywaves 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 agreementwithin situmeasurements.
