摘 要:In this paper,a new sonar imaging mode different from the cases of synthetic aperture sonar(SAS) imaging and inverse synthetic aperture sonar(ISAS) is presented,and its signal processing of imaging is mainly *** new imaging mode can be used to get the 2-D scattering characteristics of underwater targets,such as submarines,at low *** belongs to synthetic aperture imaging also,but the target moves cooperatively along a straight line while the sonar array is ***,the echo signal model is ***,the echo is processed in range and azimuth by the back-projection ***,a simulation result is *** imaging result validates the feasibility of this sonar imaging mode and that of the algorithm of signal processing mentioned in the paper.
