This white paper presents an FPGA-based architecture that hosts the processing unit of a multi-channel Frequency-Modulated Continuous Waves (FMCW) radar system. The system supports 8 channels with a peak data rate of 4.096 Gb/s.

The signal processing consists of performing a 4-step procedure on a received cuboid frame of samples: range processing, Doppler  processing, angle preprocessing and detection. To complete the processing within the frame boundary time of 30 ms, the 3 first processing tasks are allocated to hardware accelerators.

This whitepaper specifically addresses:

  • FMCW radar system concepts
  • Beat signal frame structure
  • Processing algorithms
  • Processing requirements
  • SOC-FPGA architecture and operations
