Implementation of FPGA based DSP module for CW Doppler radar: Preliminary results

This paper presents development and implementation of the Field-Programmable Gate Arrays (FPGA) of a novel Digital Signal Processing (DSP) module for the 24 GHz continuous wave (CW) Doppler radar. The module utilizes the well-known zero-crossing algorithm, relative simple signal filtering, iterative search method and the scattering centers model. The module is constructed to detect vehicles; it estimates its velocity, lane, and shape. Preliminary results of the lane and vehicle length estimation in case of two lanes are provided. VHDL code has been generated and necessary FGPA device resources for basic stages of DSP are estimated. Implementable VDHL code generation of novel algorithm is based on Simulink HDL coder.
