Abstract
We examine how to reliably exploit baseline diversity of a multichannel interferometric synthetic aperture radar (InSAR) system to overcome the layover problem. In practice, the baseline steering vectors will be imprecise, resulting in array miscalibration. We propose a nonparametric multilook approach based on robust Capon beamforming (RCB), allowing for uncertainty in the steering vectors.
