Re: Satellite Weak signal Detection

The three windows most commonly used for FFT analysis are Blackman,
Hamming and Rectangular (aka "none")

The Blackman window has the poorest frequency resolution, but has the
least amount of spectral leakage. The rectangular window (sometimes called
"none" in analysis programs)  has the best frequency resolution, but lots
of spectral leakage. The Hamming window is a compromise between the two.
Generally I use the Hamming window.
