In this paper, a new technique about long distance source localization with passive synthetic aperture sonar array is presented. At first, a sound field receiving equation for synthetic aperture sonar is derived. Then, this new method is described in detail that obtains a long distant passive azimuth, range and depth source localization by the normal-mode filter and the large synthetic aperture through horizontal moving of a short line array. The simulated results indicate that the estimation of accuracy in azimuth and range source localization is improved by this method. In addition, it is certificated that the passive synthetic aperture sonar array can realize effectively long distant source localization by normal-mode filtering method.
