Very broadband signal processing for active sonars

Stewart Glegg, Roberta W. Quant

Abstract

Very broadband sonar signal processing schemes have been developed in recent years for the investigation of ambient noise sources in the ocean. A new development is the application of this signal processing procedure to active sonar systems. It will be shown that good results can be obtained by using a correlation processor. This paper will describe a sonar developed for imaging bubbles below breaking waves from an AUV platform.
