Abstract
Multi-receiver synthetic aperture sonar (SAS) requires a large amount of computations for the imaging and the imaging effect is often unsatisfactory due to uncorrected phase errors. Two kinds of inherent phase errors were analyzed to develop improved line-by-line and dot-by-dot multi-receiver SAS imaging algorithms with a new multi-receiver SAS design. This design increases the average coverage rate and remarkably reduces the computations while improving the imaging quality. Simulation results have validated the two algorithms and the new design.
