AWR1642: FFT results from other directions

Zihan Chen

Part Number: AWR1642

According to the documentation, the board is sending chirps across different angles right? The FFT results from the GUI is just one direction, is there a parameter that we can change to get the result from another direction?

Hi,

We don't understand the question.

Which demo are you using? Are you looking at the range FFT. This provides information only about range. There is no angle information in the range fft

thank you

Sorry, let me clarify my question a bit. Does the board send the chirps in one direction and changes to multiple directions in order to detect the angle? or does it send the chirps omnidirectional? If it's omnidirectional then how did it know the angle?

Thanks,

Zihan

Hi,

I still don't understand the question

Can you please see the following training that explains how angle is detected:

Thank you

OK, it's clear to me now. Seems I had a misunderstanding over the angle detection.

Thank you,

Zihan
