IWR1843BOOST Parameter: "ElevationResolution value: NaN", which causes the z axis missing in 3D point cloud data.

Device: TI IWR1843BOOST

SDK version: 3.06

Test procedures: 1. Use hardware setup to flash the bin and load the cfg file (generated from mmWave demo visualizer 3.6.0).

2. Run mmWaveRadar() to read the properties on the device.

The value of the mmWaveRadar() output:

val =

BoardName: "TI IWR1843BOOST"

ConfigPort: "COM5"

DataPort: "COM6"

ConfigFile: "C:\ProgramData\MATLAB\SupportPackages\R2023b\toolbox\target\supportpackages\timmwaveradar\configfiles\xwr18xx_BestRangeRateResolution_UpdateRate_10.cfg"

MMWave SDK Version: "03.06.00.00"

SensorIndex: 1

MountingLocation: [0, 0, 0] (m)

MountingAngles: [0, 0, 0] (degrees)

UpdateRate: 10 (samples/s)

RangeResolution: 2.142656e-01 (m)

RangeRateResolution: 3.849848e-02 (m/s)

AzimuthResolution: 1.447751e+01 (degrees)

ElevationResolution: NaN (degrees)

MaximumRange: 1.371300e+01 (m)

MaximumRangeRate: 2.463903e+00 (m/s)

The ElevationResolution is NaN.

However, the 3D point cloud data can be correctly read from Demo visualizer but fails to be read in the MATLAB. Is there any differences from the cfg extract procedure in MATLAB?

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.
