This paper present a method to combine SAS (Synthetic Aperture Sonar) imaging of stationary targets with moving target detection and imaging. The proposed method uses a likelihood ratio for moving target detection in a wide band (WB) SAS system. For this paper, WB is defined as any systems having a large fractional bandwidth, i.e. an ultra wide frequency band combined with a wide antenna beam. The developed method combines time domain fast backprojection SAS processing methods with moving target detection using space-time processing. In the paper defocusing and detection of moving targets are investigated. Both the trajectory and the location of the moving target is given by mathematical expressions.
