Abstract
A method is provided for along-track displacement of an underwater vehicle equipped with a synthetic aperture sonar (SAS) system. The SAS system is operated as the vehicle moves through the water. Using successively-detected acoustic signals, an actual redundant phase center overlap scenario is determined that is indicative of along-track displacement of the underwater vehicle occurring between the successively-detected acoustic signals.
