Sonar for multi-aspect buried mine imaging

A buried object scanning sonar (BOSS) is designed to generate 3D images of objects at multiple aspects. Target imagery will be constructed using a sequence of acoustic echoes generated as the sonar approaches and passes the buried target by mapping target echoes to an absolute coordinate system. The horizontal and vertical resolution of targets in the field of view is controlled by pulse bandwidth. The circular receiver array is split in half and folded to form a V wing, a geometry which aids in rejecting surface scattering. Numeric modeling quantifies the spatial resolution of the imagery and the performance of the sonar for rejecting surface scatterers.
