Abstract

This paper explores the effect of squint angle on the phase errors introduced by the linear phase assumption in the polar format algorithm for SAR imaging. The maximum scene radius for an allowable phase error is derived as a function of squint angle and other parameters. Simulated phase histories for a variety of squint angles are generated and imaged to demonstrate the bound and the effects encountered when it is exceeded.
