Abstract

 This paper proposes a solution to improve the along-track resolution for multi-receiver synthetic aperture sonar (SAS) using linear frequency modulated (LFM) pulses considering the variation of acoustic velocity vector during transmission and the Doppler frequency. Based on the more complete consideration of physical processes than the conventional solution, the proposed solution can improve the along-track resolution for SAS with and without the sound velocity error. The simulation results demonstrate the effectiveness with data measured in the sea zone of Vietnam.
