Abstract
Multipath interference is a major source of interference for synthetic aperture sonar systems operating in shallow water at long ranges. In this paper we describe an iterative algorithm for blindly separating the signal from the multipath interference that uses differences in the temporal coherence properties of the signal and multipaths caused by sea surface roughness, the difficulties encountered in applying the algorithm to actual sea data, and the solutions and lessons learned.
