IWR6843ISK-ODS: unable to detect people out of 7 meters

Part Number: IWR6843ISK-ODS

The demo we are running is 68xx_3D_people_counting.Our goal is to be able to detect people within 12 meters with relatively accurate height.But no matter how we adjust our configuration file,the furthest we can detect is 7 meters.How can we make it to 12 meters with relatively good point cloud?

The configuration file we are using has been uploaded.

    Hi,

    The maximum range on that chirp is about 7 meters, you will need to change the chirp to increase the range. Easiest way to do this is to lower the chirp slope to half of its value. If you don't know what the chirp slope is, please see the SDK user's guide. This comes with the tradeoff of increasing range resolution.

    This document explains how different chirp parameters effect range, range resolution, etc.

    Regards,
