Signal processing for an active sonar system suitable for advanced sensor technology applications and environmental adaptation schemes
An overview of the basic elements of an active sonar system in conjunction with a description of the signal processing chain utilized at the NATO Undersea Research Centre for detection and localization of undersea targets is presented. Asthe focus of the Navy has shifted to the complex and volatile littoral environments characterized by high background interference, emphasis is given to the capability of advancedsensor technology to resolve left/right ambiguity in the directionof arrival and in broadband adaptation methods to enhance detection performance by incorporating in situ environmentalinformation in the processing chain. This processing was used in a series of sea trials organized and executedby the Centre, a few of which included submarine targets.
