The object of research and development is the processes of receiving, amplification, analog-digital conversion, collection, digital processing, analysis and recognition of multi-channel low-frequency signals. The subject of research is the methods and means of increasing the functionality, accuracy, speed and immunity of analog-digital systems (AC systems) of conversion and processing of low-frequency signals due to self-calibration of measuring channels, synchronous multi-channel reception, data accumulation, electronic scanning, identification of the state of objects with usingdeterministicandneurofuzzytechnologies. Research methods – modeling of processes of collection, amplification, analog-digital conversion and multi-channel processing of low-frequency signals, recovery and identification of signalsourcesusingneurofuzzytechnologiesand interference-resistant coding, modeling and experimental research of devices and system software. Structures of hardware and software components of multi-channel AC systems for conversion, processing and monitoring of low-frequency signals have been developed. The means of reception, amplification, and AC conversion have been studied. Static and dynamic characteristics of measuring channels are analyzed and new methods of their calibration are proposed.Methods of building multi-channel microphone arrays for AC systems for scanning and monitoring acoustic signals have been investigated. Algorithms and programs for scanning data processing, interference-resistant coding, audio signal recognition, and acoustic surface visualization have been developed. Designs, structural and schematic diagrams were developed, mock-ups and experimental samples of AC systems were made, and Product Description popup.authors Bilokonny Valery D. Bazhan Vitaliy V.
