Paper Abstract

The polar format approach to SAR image formation requires data to be interpolated from a warped grid onto a cartesian lattice. In general, this requires that data be interpolated between varying sampling rates. In this paper we define and justify frequency-domain optimaliy criteria for polar format interpolators and describe an approach to designing the corresponding k digital filters.
