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?
I am using the cfg setting as A."clutterRemoval 1"
I attached some pictures to understand.
IWRL6432 is located on the right side of the laptop for all pictures
The board is our customization module and the design of the EVM and the antenna is the same.
Downloaded the default cfg of motion detection (with set 1 for clutter removal).
<A>In , 6432 is facing outside the window.
- openspace is the same
<B>6432 is looking at the corridor.
<C>6432 is looking at a person in the hallway.
As you can see, in all cases the Range Profile Window has a strong signal strength for short distances near 0m.
I would like to know how to remove strong DC offset.
For example, before performing an FFT
Does sdk support how to get only the desired frequency after removing dc from rawdata by subtracting the mean value of ADC rawdata?
Regard.
