A family of cosine-sum windows for high-resolution measurements

Abstract

Special windows are used in spectral analysis to reduce the effect of spectral leakage. Windows with low sidelobe amplitude are necessary for the detection of small signals when highly dynamic spectra are concerned. The design of a family of cosine-sum windows with minimum sidelobes is described. The coefficients and selected parameters for windows with a peak sidelobe level between 43 dB and 289 dB are stated.
