IWR6843ISK-ODS: Difference perfermance between area scanner demo and 3D people counting demo

Part Number: IWR6843ISK-ODS

Hi, 

I've tried to copy the "profileCfg", "frameCfg" commands and cfar threshold from the cfg file of 3D people counting demo (ODS_6m_default.cfg) to the area scanner demo for more detected points. However, I found that the area scanner demo failed to read the data from UART buffer. But if I decrease the frame duration or increase the cfar threshold of the commands, program can output the point clouds successfully. I would like to the reason for this. It seems that the radar has better processing abilitity in people counting demo than in area scanner demo. Why the area scanner demo cannot work well with the cfg file that has the same profileCfg, frameCfg and chirpCfg and same cfar threshold as the 3D people counting demo (ODS_6m_default.cfg)  configuration file? 

Regards,

    Hello

    Please look at the post processing details and blocks of each of these demo, the difference in implementation leads to differences in results.

    If you wish to look at the basic data with standard processing please try the same Chirp on OOB demo.

    In order to understand the basic processing please check the Out of box demo's doxygen file - start with SDK user's guide to reach there.

    Thank you,
