How do I access elevation data capabilities for TI MM Wave Radar sensors (AWR1843 Boost).

The TIAWR1843Boost MM Wave Radar sensor has elevation sensing capabilities. During seup, when I create the .cfg file through the mmWave demo tool provided by Texas Instruments i can plot this data. The .cfg file stipulates that the sensor is configured for Azimuth 15 + Elevation. When i run the file though, the radar object has the elevation resolution as read only and set as NaN. It is only configurable through the .cfg file. I have verified that I am not recording any Z-axis values (only 0).

Has anybody found a work around for this?

AWR1843BOOST is not a supported TI Radar board by the support package. However, with a few minor changes to the code, you may be able to get AWR1843BOOST to function with the support package in MATLAB.

Please contact Mathworks technical support for further assistance on this.

Thanks,
