Hi.
From IWRL 6432
If you read the range fft value and the point coordinate value, there is a short range offset.
Support how to remove DC offset before fft?
Hello, I work with a writer of this thread.
We are using modified cfg from default Motion detection cfg.
However, the configuration parameter you mentioned above is 1 in defult and modified cfg files.
The DC offset we considered is apparentl not related with clutterRemoval.
I attached some pictures to understand.
IWRL6432 is placed on the right side of laptop for all pictures.
The board is our customizing module and it has the same antenna design as EVM.
I downloaded default cfg of motion detection(including set 1 for clutterRemoval).
<A> <B> <C>
In <A>, 6432 is facing outside of glass window.
In <B>, 6432 is looking in a corridor.
In <C>, 6432 is looking at a person in a corridor.
As you can see, for all cases, there is a strong signal strength for short range around zero meter in a Range Profile Window.
I would like to know the way how to remove the strong DC offset.
Regard.
