Real -time plane wave (PW) filters find many applications in 2D/3D array signal processing. In this work, novel FPGA architectures are proposed for the real-time implementation of 2D/3D FIR and IIR PW filters. Fully parallel and time division multiplexed (TDM) FIR/IIR filter structures are described for the implementation of 2D/3D frequency planar and 2D fan filters on Xilinx FPGAs. Simulations demonstrate the usefulness of the FPGA technology for rapidly prototyping real-time VLSI/CMOS implementations of FIR and IIR 2D/3D PW filters. The proposed high-speed parallel 2D IIR filter structures promise temporal band-widths of up to 150 MHz using a 300MHz FPGA chip and the proposed TDM filter structures may be used to implement 3D beam FPGA filters having a temporal sample rate of 180 KHz for a 40×40 rectangular sensor array.
