Hi, TI team,
We are using AWR1443 for gesture recognition, and we collect data in the microwave darkroom. However, when we do the distance FFT on the data, we find that there is always a large peak near the zero frequency although no gestures occur, which is converted to a distance of about 7 cm. As shown below:
Q1: Could you please tell me this peak may be caused by what? Is it possible that the hardware itself is the cause?
Q2: What method can I use to remove it?
Best wishes;
Duo
