FPGA-based real-time implementation of distributed system CA-CFAR and Clutter MAP-CFAR with noncoherent integration for radar detection

In this work, we propose real time implementation approaches of distributed Constant False Alarm Rate (CFAR) detection with noncoherent integration. The Cell Averaging (CA-CFAR) and Clutter MAP (CMAP-CFAR) detectors are employed as local detectors. The proposed architecture shows that it can be implemented with the advantages of a parallel structure and allows an important optimization of the required FPGA hardware resources utilization. The structure has been implemented using a Virtex-II XC2V1000-4FG456C FPGA board. The FPGA implementation results are presented and discussed.
