Automotive 77GHz FMCW MIMO Radar

Overview

The radar operates at 77 GHz, the standard frequency band for automotive and ADAS applications. A TDM-MIMO configuration is used to form a 16-element virtual uniform linear array, enabling high-resolution angle estimation.

Key Features

  • 77 GHz FMCW radar waveform simulation
  • TDM-MIMO radar with virtual antenna array
  • Range–Doppler processing using 2D FFT
  • 2D CA-CFAR target detection
  • Angle-of-arrival estimation using:
    • FFT-based beamforming
    • MUSIC
    • Spatial Smoothing MUSIC
  • Comparison between conventional and high-resolution AoA methods

Algorithms Used

  • Fast Fourier Transform
  • Range–Doppler Processing
  • Cell-Averaging CFAR
  • Beamforming
  • MUSIC Algorithm
  • Spatial Smoothing MUSIC
