Multiplier-less Correlator for Noise SAR Imaging

Abstract

Correlation function estimate using one-bit reference signal is described and results of FPGA-based implementation of multi-channel time-integrating correlator without multiplication operation (multiplier-less correlator) is described. Results of experimental evaluation of the suggested multiplier-less relay correlator implemented in Innovative Integration X6-1000M board with Xilinx Virtex-6 FPGA and arbitrary waveform generator Euvis AWG472 are presented.
