Thanks a lot ! The 'scallopping loss' solves the problem. However this is
still "black magic" as I do not fully understand the bin centered tones
idea. My data is a random data ,radiation gathered by the NA through
waveguide from the antenna. How can I know that those signals are not bin
centered ? And why halfway ? Can't they be somewhere in-between ?

Also question about windowing. The gain I lose when I am using window
different from rectangular one is not constant along the spectrum ? So,
does the coherent gain coefficent gives back the oryginal amplitude or it
is burdened with some error ?
Best regards,
