Abstract :
The Cassini radar´s synthetic aperture radar (SAR) ambiguity analysis is unique with respect to other spaceborne SAR ambiguity analyses owing to the non-orbiting spacecraft trajectory, asymmetric antenna pattern, and burst mode of data collection. By properly varying the pointing, burst mode timing, and radar parameters along the trajectory the study shows that the signal-to-ambiguity ratio of better than 15 dB can be achieved for all images obtained by the Cassini radar
