Abstract

The paper suggests the technique for the spectral analysis of polyharmonic signals in Fourier basis that can be used in hydroacoustic monitoring tasks, radiolocation, radiocommunication and measurement capabilities. The technique decreases sidelobes levels without deterioration in the spectral analysis resolution, and increases signal-to-noise ratio. The technique was compared with other window functions. Main advantages of the suggested technique were defined.
