Abstract
Spectral analysis is concerned with estimating a signal´s power distribution as a function of frequency. D.J. Thomson´s multi-window method (1982) is one approach to this problem that uses the discrete prolate spheroidal sequence family of windows which maximize total sidelobe energy. This criterion is inflexible and inappropriate for some applications. An alternate window family based on a weighted peak sidelobe amplitude criterion is proposed. These windows offer greatly reduced peak sidelobes and afford precise control of the sidelobe envelope structure. A design procedure is presented along with examples of the new window family
