An improvement of the discriminating capability of the active sonar by optimization of a criterion based on the Cramer-Rao lower bound

This study is a contribution within the framework of detection of underwater targets using active sonar. This paper aims at proposing an original method allowing a great improvement of the sonar performances. This technique uses a filter, determined by optimizing a criterion based on the Cramer-Rao lower bound. Experimental results are proposed and compared with other approaches.
