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, Piotr
