Hi,

I modified the AoA code，added doppler compensation for 1 Azimuth Tx and 1 Elevation Tx，

After measurement，I found the initial bias is larger, but the differences of corner height are similiar

(P0-P1 & P1-P2). Is this normal for larger initial bias?

Thank You

Hi,

There are several things to consider

First, which Antenna did you decide to enable for Azimuth? Green or Red.

Second,

For doppler compensation, you should not need the code section in if ()

thank you

Hi,

Because I want to get larger Vmax, I change the chirp profile as attached pic.

So my doppler compensation is modified to delta/2. Is there anything wrong?

Thank you

Hi

So is your main goal increasing the Vmax?

Thank you

Hi
Yes, My goal is increasing the Vmax .
I am not sure the change and result of experiment are correct.
Thank You

Hi,

I checked with developer of the mmwave sdk demo and he mentioned that for 2 Antennae, you should not need section of the code " if(numVirtualAntElev>0)"

Thank you
