IWR6843ISK: Ways to Expand Beamforming Range

Hi,

You could add more angles to the scan, but beamforming to angles as large as 60 degrees may result in unintentional side-lobes. I am looping in a co-worker to comment.

Hello,

I'm leaving a comment to ensure accurate communication.

I would like to change the beamforming as shown in the above image.

Is this possible?

Hi, Joohee:

It is totally fine.  Just remember to filter out the detected points based on your steering zone.

Hello,

Thank you for the response.
Then, if I want to change the beamforming angle from 22.5° to 30°, how can I do that?

HI, Joohee:

Could you describe the problem in words?  I am not sure what is the problem from the figure itself.

Hello,

Here are the test results conducted using the visualizer in an open field:

We used a custom board based on the IWR6843ISK and applied the long range people tracking configuration. In the absence of people or moving objects, a point cloud continuously appeared from 0 to 100 meters along the maximum angle line of the beamforming.

We consider this to be noise.

We want to identify the cause of this noise and find a solution to resolve the issue.

Hi, Joohee:

Is this false detection happening with original binary and default configuration?

Hello,

I used the original binary.
