AWR1843: What is the minimum distance AWR1843 can detected using lab demo mrr?

Part Number: AWR1843

Can you please advise what is the minimum distance AWR1843 can detected using lab demo mrr?

I tested AWR1843 by puting my hand in front of the AWR1843Boost, when the distance reduces to ~4cm, it seems the device could not detect the object.

Kind regards

    Hi Lei,

    Please make sure that the distance to measure is greater than the range resolution of the device (4.3cm in this case for USRR). Less than 4cm is too small a gap between the sensor and the object for it to be able to resolve it. The range config can be found in the chirp definition.
