The project aims at solving the fundamental scientific problem of increasing the noise immunity, dynamic accuracy and sensitivity of digital communication systems, telecommunications, radar and radionavigation by developing the theory of invariant piezoresonance devices for the formation of bispectral-organized signals in the mode of multi-frequency excitation of a quartz resonator and the creation of new bispectral methods of digital modulation, detecting and differentiation signals over background noise in the information-measuring systems.
As a result of the project: the theory of formation, transmission, detection and differentiation of digital bispectral-organized signals is created; developed noise stability towards additive and impulse noise, fading effects and hardware phase fluctuations (jitter) in the communication channel bispectrum-organized methods of modulation based on orthogonal synthesis bispectrum-organized triplet-signals and their differentiation through new test statistic of order - estimates of peak magnitudes of bispectral density; the methods of generating signals polyfrequency triplet-based precision multifrequency oscillatory systems robust to destabilizing factors.
Obtained as a result of the project, new conceptual provisions, approaches and methods are fundamental to the theory of potential impedance of digital signal transfer systems, the theory of self-oscillating systems, nonlinear spectral analysis of signals, synthesis of multi-frequency quartz oscillation systems for generation of triplet signals. The implementation of the proposed noise immune bispectral-organized methods of modulation and signal processing is appropriate and is promising in the automated radar detection systems for moving ground and air targets; radar alarm systems, military radiotechnical systems for observing and recognizing mobile ground objects in conditions of increasing requirements for increasing Ukraine's defense capability
