The article deals with the problems of designing multi-channel high-frequency signal generators for the transceivers of unmanned aerial vehicles (UAVs). It is proposed to use high-speed digital-to-analog converters to increase the output frequency and improve the noise characteristics of UAV transceivers. The possibility of using special operating modes used in modern high-speed direct-to-analog converters (DACs) for digital generation of broadband signals is shown. Mathematical models of noise characteristics at ...

The capabilities of existing intelligent decision-making systems are very limited, so for the successful solution of a wide class of tasks based on unmanned aerial vehicles (UAVs) reliable communication with the group of aircraft is required. For communication between individual UAVs, as well as UAVs with a ground station, Flying Ad Hoc Networks (FANET) and flying sensor networks (FSN) are used. Known works devoted to the development and research of such networks consider predominantly radio communication at the p...

The article is devoted to the development of the algorithm for express analysis of the state of human functional systems, taking into account the data of goniometric control. The analysis of electrophysiological correlates of movements is given. The features of occurrence of bioelectric signals of brain centers and muscle neurons are analyzed. Based on the analysis it is established that for more effective study of the pathology of the musculoskeletal system it is necessary to carry out goniometric control togethe...

The article discusses the method of the estimation of the permissible degree of the deflection of the spine and of bias of vertebrae. The proposed method is based on measurement of steering angles and degree of deviation of vertebrae by accelerometric transducers, application of neural network algorithms of the processing of capture data for adapt of the system of the diagnostics and of the rehabilitation under patients with different physiological characteristics and disorders of the spine and musculoskeletal sys...
