An omega‐<i>k</i> algorithm for multireceiver synthetic aperture sonar

In this Letter, the authors present a novel imaging algorithm for multireceiver synthetic aperture sonar (SAS). The Loffeld's bistatic formula (LBF) including quasi-monostatic (QM) and deformation (MD) phases is first reformulated into range-variant range-invariant phases. After compensating phase, subsequent steps are extended Stolt mapping each SAS. Based on simulations, presented method can also provide high-resolution result which similar to that of back projection (BP) algorithm.
