Hello,
I am creating my own post process script and i am facing an issue concerning peaks at the begining and end of RangeFFT, even if i don't have obstacles in front of the radar
This uploaded image is the RangeFFT for one chirp. We can see the peak at 0 frequency.
When i put 2 obstacles in front of the radar, one at 2 meters and the other one a 4 meters i get the following rangeFFT
Two peaks are visibles at 2 meters and 4 meters but close peak still present.
I have a complex1x setup.
The peak at the end seems normal cause with complex1x, we have to cut range FFT at 0.9*fs and this peak is inside the last 10%
Someone has a explanation concerning this peak and how to minimize it ?
Is a calibration usefull to reduce this peak?
thanks
