IWR6843ISK: Target's direction of movement and doppler velocity

Hi,

Apologies for the delayed response. I recommend reading the Fundamentals of mmWave radar sensors document here: https://www.ti.com/lit/wp/spyy005a/spyy005a.pdf?ts=1686584590865&ref_url=https%253A%252F%252Fwww.google.com%252F 

This document explains how our velocity calculations are completed. Please let us know if you have further questions.

Regards,

Tim

Hi,

I understood that the doppler velocity estimation in the mmWave radar sensor can be estimated by the phase difference of the chirp within the frame.

I wonder if the chirp phase difference is the same in the above situation (two targets each moving horizontally and vertically at the same speed).

Since the chirp interval is very short, the phase difference is considered to be the same regardless of the direction of movement. Is that correct?

Thanks.
