ABSTRACT:
Compensating for motion of the host vehicle in a synthetic aperture radar system includes collecting inertial data with an inertial navigation system during an imaging period in which a synthetic aperture radar pulse is directed to a target. During the imaging period global positioning system corrections to the inertial data are collected. A smooth representation of the global positioning system corrections is formed and then the smooth representation of the global positioning system corrections is applied to the inertial data after completion of the imaging period.
