AWR1243: Ghost signal occurs when the target is close.

Hi,

I am trying to use MIMO mode of cascade radar. After running "Cascade_Configuration_MIMO.lua" and "Cascade_Capture.lua", I can see the PostProc results.

However, I think that the radar doesn't work well... the ghost signals exist.

I tried to capture a corner reflector (range ~= 4m)

but in the postproc:

However, I found that the ghost signals exist only when the range is under approximately 5m.

In this situation (range ~= 6m)

In the PostProc, there are no ghost signals. I think it works well.

I want to know the reason why the ghost signals occur, only when the range is under 5m.

Do you have an idea?

Seongmin.
