The basic principle of synthetic aperture sonar (SAS) is to record the signals received on a short physical array as it proceeds along the track, and the signals can then be combined coherently to form a long array. Conventional time delay and sum algorithm (TDS), which compensate for the echoes phase of each pixel before being summed coherently, requires too much computation to be practical in many...
In marine engineering surveying, when we control a towed synthetic aperture sonar in an uniform linear state, the survey results appear with many motion errors because of the random and multi-dimensional position fluctuation of the towed platform. A motion error estimation method based on seafloor tracking is studied in order to estimate these errors. Firstly, sonar echo data is obtained by wideband...
