Abstract
The systems and methods described herein relate to systems and methods for synthetic aperture sonar (SAS) or radar including seismic surveying. The systems may include a first number of a plurality of acoustic transmitter elements mounted on one or more vehicles, and a second number of a plurality of acoustic receiver elements mounted on one or more vehicles. Each of the vehicles may include a processor having a synthetic aperture image of a portion of the underwater terrain. The synthetic aperture image may include acoustic data obtained from prior synthetic aperture sonar imaging of the underwater terrain. The plurality of vehicles are arranged to form a planar synthetic aperture sonar array having a third number of phase centers. The third number of phase centers is equal to the first number multiplied by the second number. The transmitters in such systems may be configured to generate orthogonal acoustic signals.
