Opis:: The subject of the paper is the application of digital signal processing (DSP) to nonlinear hydroacoustic, acoustic and mechanic phenomena investigations. To provide such investigations a spectrum analyzer with additional functions of polyspectra and virtual input channel is proposed. The mathematics, equipment and programming of the analyzer are discussed. It is shown how the analyzer enables to detect and to explore the random impulse sequences combined with one another and with Gaussian noise, to separate the oscillations having close unstable frequencies, to observe the nonlinear interaction between oscillation modes, to detect the noise emission accompanying the oscillation mode energy dissipation.

Opis:: The subject of the paper is the application of digital signal processing (DSP) to nonlinear hydroacoustic, acoustic and mechanic phenomena investigations. To provide such investigations a spectrum analyser with additional functions of polyspectra and virtual input channel is proposed. A serial number instruments and systems has been created on the base of development of the complexes which can evaluate the above mentioned high order spectra for analysing hydroacoustic and hydrophysical signals or electromagnetic signals of navy objects. Several modes of the analysers architecture are accomplish in our Institutes: full hardware with build-in microcomputer, external device interfaced with PC and base on 16-bit Analog Devices δ-∑ codecTM environment mount in PC which works in DOS or WindowsTM mode. These complexes were used for development the testing environment for navy polygons and may be use in navy system of the barrier defence.
