IWRL6432BOOST: Doppler of point cloud data

Yuichi Morita

Part Number: IWRL6432BOOST

Tool/software:

Hello Team,

I use Mmwave Demos of Motion and Presence Detection.
Radar can detect moving objects, but I can not cheak doppler in saving data of Industrial Visualizer.
In saving data,there are point cloud data,but doppler is 0 in all points.

I want to get value of doppler.

I refer to this page, but I can not solve my problem.

e2e.ti.com/.../iwrl6432boost-i-am-curious-about-the-z-value-and-doppler-value-of-the-detected-output-data

Do you have any ideas to solve my problem？

Regards

Hello Yuichi,

Which configuration file are you using? Its possible the Doppler FFT size is not large enough, velocity resolution is very low, and/or minor motion velocities are being rounded to zero.

Hello Pedrhom,

Thank you for reply.

I use below configuration file.

MotionDetect.cfg

C:\ti\MMWAVE_L_SDK_05_05_03_00\examples\mmw_demo\motion_and_presence_detection\profiles\xwrL64xx-evm

Targets have minor motion velocities, so velocities may be rounded to zero.

I need values of velocities.

Best Regards,

Yuichi

Hello Yuichi,

What kinds of velocities are you trying to detect? For example the speed of a walking person? The speed of a vehicle? Have you tried PresenceDetect or other configurations?

Best Regards,
