Wideband 32-element 200-MHz 2-D IIR beam filters using ROACH-2 Virtex-6 sx475t FPGA

Abstract

Two-dimensional (2-D) IIR beam filter applications operating in ultra wide-band (UWB) radio frequency (RF) range requires hardware capable of handling high speed real-time processing due to its operation bandwidth lies in megahertz or gigahertz range. Two-dimensional IIR beam forming is used mainly for applications such as communications, radars and detection of directional sensing. A systolic architecture is proposed for the real-time implementation of the 2-D IIR beam filter. This the first attempt of evaluating the prospect of practical implementation of such a beam filter capable in ROACH-2 hardware platform which is equipped with a Xilinx Virtex-6 sx475t FPGA chip, widely used in the field of radio astronomy reaching upto 200 MHz operating frequency.
