Abstract
Results of thorough program synthetic aperture modeling intended for clearing up the influence of some interferences on the quality of synthesis, in particular, the additive noise and yaw of a vehicle with hydrophones as most significant ones, are described. It is proposed to compensate for the impact of vehicle yaw on the quality of synthesis by additive correction of the yaw angle by the criterion of maximizing the quality of the peak characterizing the observed pin-point object.
