Abstract
A system and method to detect an object buried beneath the seabed are described. The system includes a moving platform, a low frequency signal source coupled to the platform to transmit a low frequency signal to an area of the seabed, and a laser Doppler vibrometer (LDV) coupled to the platform to transmit a plurality of transmission beams to the area of the seabed at a respective plurality of angles at each position of a plurality of positions of the platform over the area. The LDV includes a plurality of receivers that receive a respective plurality of reflection beams resulting from the plurality of transmission beams. A processor develops a three-dimensional image that indicates the object, the processor determining a reflection value at each point of the three-dimensional image as a coherent combination of reflection from the point contributing to each of the plurality of reflection beams.
