Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] Not Applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH

[0002] Not Applicable. FIELD OF THE INVENTION

[0003] This invention relates generally to synthetic aperture sonar and, more particularly, to a method and system for synthetic aperture sonar that provide improved spatial position of a moving sonar array used in a synthetic aperture sonar. BACKGROUND OF THE INVENTION

[0004] Active sonar transmits a signal into the water, and receives echoes from targets in the water. The targets can include, but are not limited to, submarines, torpedoes, tethered mines, bottom mines, cables, and bottom features such as hills, trenches, and the bottom surface.

[0005] Active sonar systems have a variety of configurations. Bistatic active sonar systems have an acoustic transmitter separate from an acoustic receiver. Monostatic active sonar systems have an acoustic transmitter co-located with an acoustic receiver.

[0006] The acoustic receiver po...
