AWR1642: Point cloud data with apparent velocity components appears during a test in a scene where there are no moving targets

Hello Miles,

Can you tell me the exact usecase for this?

Hello Miles,

I didn't really understand from the picture. Is this for automotive, industrial? Want to know the end use case so I can assign to the right team member.

Hello,

This is for automotive applications. Recently, we've found that the radar generates point cloud data with apparent velocity components in certain stationary scenarios, which is why we're raising this issue now.

Hi Miles,

I see that signal in highlighted area is equal to the noise floor. What is the difference between the detection at 0th doppler bin and the highlighted area? What is the difference between signal strength in the highlighted area and the noise floor?

Hi Bobba,

Thank you for your reply.

The highlighted area shows a peak that is close to the noise floor, but a peak can be clearly observed on the Doppler spectrum.

However, in reality, there is no moving target inside this container house, so theoretically, there should not be a peak with velocity.

Can you please provide answers to the above questions?
