Performance of underwater adaptive array including mutual coupling effects

Abstract

In this paper, the mutual coupling effects on the performance of underwater adaptive arrays are analyzed. This study manifests the discrepancies between cases of considering and ignoring the mutual coupling effects. The least mean square (LMS) based adaptive array is utilized to illustrate the mutual coupling effects. Numerical examples show that the performance of an underwater adaptive array can be improved as mutual coupling effects are considered. The consideration of mutual coupling effects is necessary in analyzing underwater adaptive arrays.
