چکیده :

Abstract— The primary objective of this article is to enhance phase error correction in critical directions. Previous studies indicate that phase correction methods face significant limitations when addressing unwanted platform movements, leading to a degradation in output image quality. This research proposes a novel approach that focuses not solely on improving phase correction techniques but on achieving an efficient geometry for hydrophone array arrangement. The innovative goal is to increase the likelihood of receiver presence and improve the reception of returning signals, which can substantially mitigate the adverse effects of phase error. This issue is addressed by reducing the impact of unwanted impulses in critical degrees of freedom, complementing existing phase error enhancement methods. The findings suggest that optimizing hydrophone array configurations can lead to significant advancements in synthetic aperture sonar (SAS) applications, ultimately improving imaging performance and accuracy.
