The search for weak spectral lines with SNR ≈ 1 in noisy gravitational data is difficult, since the analysis methods used so far do not exploit all available information. The vector FFT presented here reduces the noise level and narrows the FWHM of all spectral lines by taking advantage of the phase information of the FFT.
