SAR imaging by ?? migration

Abstract A new method of processing synthetic aperture radar (SAR) data was originally developed by a group of geophysicists, who use seismic migration to generate seismic images of the Earth. Called here ω—κ migration, it has several advantages over more traditional methods of forming SAR images; they all arise because this method provides a mathematically exact solution to the imaging problem, in that the emitted waves are not being treated as plane waves. This paper discusses how migration processing can be applied to chirped radars; how it applies to spotlight data; and how to correct for non-uniform motions of the SAR platform.
