Hi Jasper,

If a maximum range of 6meters is desired, the mmWave radar could be tuned for that range via the cfg file that is sent over during startup. Would this work for you customer's use case?

Hi Jasper,

There is quite a few components to radar tuning, so I will provide a few resources.

This doc provides background on the math and logic behind different chirp parameters.

This guide provides documentation on what all the different parameters in the .cfg file represents, refer to section 3.4 "Configuration file format":
https://software-dl.ti.com/ra-processors/esd/MMWAVE-SDK/03_05_00_04/exports/mmwave_sdk_user_guide.pdf

This tool can be used to provide some assistance with calculating what impact the various parameters will have on different performance characteristics:
