Both across-track and along-track interferometric systems allowing to recover the height profile of the ground or the moving target radial velocities respectively are considered. The joint use of multichannel configurations which can be either multifrequency or multi-baseline and of classical or Bayesian statistical estimation techniques allows to obtain very accurate solutions and to overcome the limitations due to the presence of ambiguous solutions intrinsic in the single-channel configurations. The improved performance of the multichannelbased methods with respect to the corresponding single-channel ones has been tested with numerical experiments on simulated data. Keywords and phrases synthetic aperture radar interferometry statistical signal processing Markov random fields. 1. INTRODUCTION Synthetic aperture radar interferometric InSAR systems use more than one antenna typically two which can be displaced along the platform moving direction
