Imaging radar using cascaded mmWave sensor reference design


Design files


The cascade development kit has two main use cases:

  1. To use the MMWCAS-DSP-EVM as a capture card to fully evaluate the AWR2243 four-chip cascade performance by using the mmWave studio tool, please read the TIDEP-01012 design guide.
  2. To use the MMWCAS-DSP-EVM to develop radar real time SW application, please read the TIDEP-01017 design guide.

This reference design uses a cascaded imaging radar radio-frequency (RF) system. Cascaded radar devices can support long-range radar (LRR) beamforming applications, as well as medium-range radar (MRR) and short-range radar (SRR) multiple-input multiple-output (MIMO) applications with enhanced angle-resolution performance.

The AWR2243 cascade radar RF development kit has been used to estimate and track the position (in the azimuthal plane) beyond 350 m with a multidevice, beamforming configuration. Additionally, this system has demonstrated azimuth angular resolutions as small as 1.4 degrees in a time-division multiple access (TDMA)-MIMO configuration.

  • Two- or four-chip frequency-modulated continuous-wave (FMCW) radar sensor for LRR, MRR and SRR applications
  • Detect objects (for example, cars and trucks) at a distance beyond 350 m with range resolution of 35 cm; human radar cross-section (RCS) objects detectable at a distance of 150 m
  • Antenna field of view (FoV) ±70º with angular resolution of approximately 1.4 degrees
  • MATLAB® MIMO and beamforming example code provided
  • AWR2243-based demonstration design
  • Cascaded imaging radar front-end beamforming and MIMO configuration fully explained
