TRANSDUCER-SHAPE OPTIMIZATION FOR ANGLE ESTIMATION OF A BROADBRAND MONAURAL SONAR SYSTEM
Abstract
In this paper we describe a procedure for the search of the optimal transducer geometry for a monaural, broadband sonar system. We restrict ourselves to a simple transducer morphology that can be technologically realized: a radially symmetric two-dimensional piston transducer with adaptable electrode shape. We use a genetic algorithm to obtain the `optimal' geometry, and show that the generated transducer performs significantly better in simulated localization experiments.
