Hi Team,
Our customer noticed some loud noise on the AWR1642Boost. According to our customer,
I have attached an image of the noisy signal. As you can see it is just random noise in these displacement phase values. As I mentioned before I am trying to get phase value from 1 chirp in every frame by getting the complex value of the range fft peak in target bin. I obtain a large vector of complex values and use arc tan demodulation to get the phase. Unwrap is used to remove discontinuities. Then, the difference between successive phases can be used to get the displacement phase. However, the results are very noisy as it can be seen. Correct results should less noise and able to visualize some correlation of respiratory and heartbeat displacements in the signal. It is some kind of noise in the raw data obtained from the radar.
Regards,
Danilo
