IWR6843: Long Range People Detection | Setup Configuration

Part Number: IWR6843

Tool/software:

Hello TI Team.

I am supporting an application where the target is to detect the presence of people in an open area with sparse vegetation using the mmWave technology. The evaluation kit IWR6843ISK is being used and it is connected to a Raspberry Pi (via USB), which gets the data and processes it, triggering the detection events.

The eval kit is running the Long Range People Detection firmware example (2D 100 meter configuration). During the testing in the field, several false positive events are being triggered, especially when it is raining.

QUESTION: Is there an AN or any other material which provides some guidance on how to better configure the Long Range People Detection firmware?

Thanks in advance.
