A reconfigurable 2D convolver for real-time SAR imaging

A novel architecture for real-time synthetic aperture radar signal processing that achieves real-time processing by using a recently proposed signum coded algorithm and time domain processing, is presented. New architecture is completely parallel and can be dynamically reconfigured in order to use different dimensions of data and filter matrices. A standard-cell VLSI implementation is presented and its performances are evaluated through circuit simulations.
