Abstract

Abstract

The paper proposes a scheme for the realization of multi-beam Synthetic Aperture Sonar (SAS) based on the multi-beam bathymetry and aperture synthetic principle, designs a new multiple receiver array structure, deduces correlated math model, and simulates the dot-by-dot imaging algorithm according to the array structure. Computer simulation results show that: compared with multi-beam bathymetry sonar, the new scheme can remarkably improve the along-track resolution, and compared with conventional SAS, the new scheme can get more information of the target and enhance the imaging quality.
