Abstract

Based on the model of multibeam synthetic aperture sonar (MBSAS) and the principle of multiple subarray interferometic, a high resolution multibeam synthetic aperture interferometric imaging algorithm was proposed. Firstly, the algorithm got the target rough position via the Back-Projection (BP) algorithm of single array element and the multiple beamforming of the whole array. Then the multiple subarrays interferometry was adopted to get the more accurate Direction Of Arrival (DOA). The algorithm solved the problem that the imaging resolution was limited by the number of beam in the MBSAS BP imaging algorithm. The simulation shows this new method can obtain the more accurate target position and higher resolution images comparing to the traditional MBSAS BP imaging algorithm.
