CHAOTIC AND NOISY SIGNALS, DIGITAL GENERATION AND PROCESSING OF RANDOM SIGNALS, CORRELATED SIGNAL PROCESSING, SPECTRAL INTERFEROMETRY, NOISE AND QUANTUM RADAR, APERTURE SYNTHESIZED RADAR. The objects of research are dynamic chaos in radiophysical and electronic systems, in particular in resonators with nonlinear reflection and multi-channel delay feedback, random signal generators for noise and quantum radars, noise systems of radio images. The purpose of the work is to obtain new fundamental knowledge about the nature of dynamic chaos phenomena in radiophysical, optical, and electronic chaotic resonance systems; development on this basis of new methods of random signal generation in oscillating systems of microwave, terahertz and optical wave ranges; development of new methods of reception and processing of random signals for noise systems of various purposes. Research methods are based on the theory of nonlinear dynamic systems, the theory of classical and quantum chaos, known and established methods of digital generation and processing of random signals, as well as methods of modern noise radar. The work is characterized by a combination of theoretical and experimental studies of the considered systems. New principles of generating chaotic signals in resonators with nonlinear wave reflection have been developed; methods of digital generation of pseudorandom signals using a reprogrammed logic integrated circuit (Field Programmable Gate Array, FPGA) and direct digital synthesis techniques. The possibility of creating new systems with random signals for the formation of radio images and radio films, as well as communication systems for transmitting and receiving information between moving vehicles is shown. Corresponding theoretical and experimental studies have been conducted. Product Description popup.authors popup.nrat_date 2023-05-29 Close
