AbstractThis paper gives an analysis of range ambiguities in the extended high incidence angle beams of RADARSAT. These beams were not part of the original imaging specification for RADARSAT but were included as experimental beams for research purposes because they could offer imaging geometries that might excite applications of RADARSAT for which their shortcomings might not be critical.

A scene from eastern Canada off the coast of Nova Scotia shows ghost images of the mainland in the ocean. Under the low wind conditions that prevailed, it is shown that range aliasing can account for the features shown and that the level of the ambiguous backscatter varies across the swath from -6 to -14 dB in the case of the EH4 beam studied.
