Abstract

Abstract

To address the problem that the aperture-dependence of ‘non-hop-go-hop’ time in the existing imaging algorithm for the multiple receivers Synthetic Aperture Sonar(SAS) is ignored and brings the delay error, a imaging algorithm based on the reference range history is proposed in the paper. Firstly, the shifting relationship between the reference receiver and the other receivers is used to derive the approximated range history of every receiver, which conquer the problem of ignoring aperture-dependence of ‘non-hop-go-hop’ time. Then, after the echo signal of each receiver is shift to the same beam centre range, the undersampling multiple receivers signal can be transformed into the single receiver signal by the azimuth reconstruction, which can be processed by the monostatic imaging algorithm to get imaging result. Finally, the validity of proposed algorithm is tested by the simulation experiments and real data.
