Abstract
The HF/LF SAS is a high resolution SAS developed by COASTSYSTA and Northrop Grumman for the shallow water (SW) and very shallow water (VSW) regimes. This sonar suite has recently been delivered to COASTSYSTA and it is currently undergoing field testing. This article describes this sonar and the type of resolution and acoustical images which are expected from this sonar. The application of this sonar to the SW and VSW regimes required the development of a novel method of motion compensation. A description of this method and the type of accuracy's expected from this technique are presented. Finally, a look at future broad band system and their predicted performance is presented.
