research on the dot-by-dot imaging algorithm for multi-beam SAS based on a new array configuration

摘要：

This paper proposes a scheme for the realization of multi-beam synthetic aperture sonar (SAS) based on the multibeam bathymetry and aperture synthetic principle, designs a new multiple receiver array structure, deduces correlative math model, and simulates the dot-by-dot imaging algorithm according to the novel array structure. Computer simulation results have tested the correctness of theory analysis and the efficiency of algorithm, the 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, thereby enhance the imaging quality.
