AWR1642BOOST-ODS: Heatmap calculation - Obstacle Detection Reference Design Using 77-GHz mmWave Sensor

Part Number: AWR1642BOOST-ODS
Other Parts Discussed in Thread: TIDEP-0104

Dear team,

I don't quite understand how the Range-Elevation angle heat-map and Range-Azimuth angle heat-map are calculated.
The white paper "TIDEP-0104" describes the algorithm used for this as covariance beamforming or Capon
beamforming. Which of the two algorithms is used as standard?
As input the algorithm receives the result of the Range-FFT.

Do you have further literature/tutorials for me, which could help me understand the algorithm?

Thanks in advance and best regards

I'm afraid that exact documentation may not be available but I would suggest you refer mmw demo doxygen document which has many of this algo there.

Hello Jitendra,

i already checked out the mmw demo doxygen, but i could not find answers .
The "tidep-0104" has its own doxygen documentation, but it is not build yet and i couldn't find a doxyfile.
I tried to reconstruct the doxyfile, but wasn't able to do so.

Can you please get me the doxyfile or the doxygen documentation?

Thanks in advance and kind regards
Michael

Hi Michael,

Doxygen file is not available for this demo. However, you can refer to the source code comment to get the details required.
