Abstract :
In this paper, an airborne Ka-band (35GHz) FMCW interferometric synthetic aperture radar (InSAR) and its preliminary processing results are presented. Among the issues that had to be addressed in the processing of the SAR imaginer was the correction of range ambiguities through the use of a phase gradient algorithm. In this paper, the results of the 35 GHz InSAR are presented to demonstrate the height mapping capability of the UMass 35 GHz radar system.
