Apply Zoom FFT to impove the angle accuracy

Jun Fang

Hi,

Zoom FFT can improve resolution of FFT which includes both frequency and phrase. Since it has been proved great ehancement for the range accuracy, e.g., from cm to mm.

I'm wondering if it can also increase the angle accuracy as well. If Yes, how much improvement will be achieved in theory? Thanks.

Hi,

Angle accuracy will depend on the antenna design. The better the Rx/TX isolation for the antenna, the better the angular accuracy

Zoom FFT will not improve angular accuracy.

thank you

Thanks. So the RX/TX isolation is the biggest factor.

In a given RX/TX isolation, Does Zoom FFT improve angular accuracy?

No,

The Zoom FFT only improves range accuracy

thank you
