FPGA-based time-integrating multichannel correlator for Noise Radar applications

Abstract

Multichannel time integrating correlator has been implemented in FPGA Xilinx Virtex 6 using X6-1000M board from Innovative Integration Inc. A new implementation of relay correlator for FPGA has been suggested and tested. The approach suggested enables exclusion of multipliers usage that saves FPGA resources, which, in particular, allows increasing of the working range of Noise Radar. The developed correlators have performances sufficient for design of noise radar according to the software defined radar concept, such as homeland security sensors, ground based SAR, and radar tomography enabling generation of 2D and 3D coherent SAR images and radio-films.
