摘要：
To solve the problem that the inertial navigation system data is difficult to be used directly in synthetic aperture sonar (SAS) imaging, a model for solving the motion errors was established, using the inertial navigation system, and a point-by-point motion compensation algorithm for multiple-receiver SAS in the non-stop- hop-stop mode was proposed. And the problem of fusion of inertial navigation system data and SAS data was solved. Then, the effects of three types of motion errors, surge errors, sway and heave errors and angle errors, on the imaging were analyzed through simulation. Finally, the sea trial data imaging processing shows that the proposed algorithm can improve the imaging quality, which verifies the effectiveness of the proposed the method of solving the motion errors and motion compensation algorithm. © 2020, Editorial Board of Journal of Huazhong University of Science and Technology.
