Embodiment Construction
[0052] A synthetic aperture sonar joint motion compensation method and system provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0053] The invention proposes a multi-sensor based synthetic aperture sonar motion compensation method, which is used to estimate and compensate the error caused by the motion of the sonar base array, and improve the imaging quality of the synthetic aperture sonar. The sensor mentioned here is generalized, and the sonar array itself can also be regarded as a sensor, and the echo data received by the sonar array can also be used as an information source for motion compensation. From the perspective of implementation, the synthetic aperture sonar motion compensation can be divided into motion error estimation and motion error compensation, wherein the motion error estimation is the key of the method of the present invention. The specific implementation of the metho...
