Beamforming for Sonar Based on Highlight Model

Abstract

The highlight model can be expressed by transfer function when the echoes obey the linear acoustic law. This paper aims to present a new beam forming method based on highlight model via the combination of transfer function of highlight model and beam forming technology. Information such as the azimuth of target can be obtained by beam forming using a few highlight. And this paper simulates the beam pattern by using conventional beam forming under the condition that there does not exist interference, and Minimum Variance Distortion less Response beam forming under the condition that there exist the interference. The results show the feasibility of this method.
