  • Descrição: The spectral digital signal processing methods for narrow‐band acoustic signals are considered. One of the main parameters of spectral signal processing, spectral analyze resolution, is optimized earlier but only by using the energy criterion of optimality—the signal/noise ratio. In the present work, an optimization problem for the spectral analyze resolution was formulated and solved by using probability criterion of optimality, false‐alarm probability for signal detection. It was considered a mixture of narrow‐band signals and noisy interference and two important practical cases: (1) known center frequencies of signals; (2) unknown center frequencies of signals. A new nontraditional common results is obtained; it is shown that under final signal duration, optimum resolution mismatches substantially with a width of spectral signal density which allows considerable simplification hardware realization of spectral digital signal processing methods.
