Abstract :
This paper presents a method for resolving Doppler centroid ambiguity in ScanSAR data. The method used is a generalisation of the multiple PRF technique, C. Y. Chang et al. (1992), where the different PRFs illuminate adjacent subswaths rather than having the same look angle. The method is applied to a Radarsat ScanSAR data set
