METHODS OF COMPLEX PROCESSING AND INTERPRETATION OF RADAR, ACOUSTIC, OPTICAL, AND INFRARED SIGNALS OF UNMANNED AERIAL VEHICLES

Abstract

Unmanned aerial vehicles (UAVs) are currently widely used in solving a wide range of useful tasks, however they can pose an active or passive potential threat to various areas of human activity - economic, everyday life, and military domains. Radar, acoustic, infrared, and optical means are currently used to detect presence and measure the coordinates of UAVs. Since the areas of capabilities of various methods do not coincide, a prerequisite appears for the joint use of systems of various types to expand the set of measured parameters, the range of observed ranges, and to increase the information content of the obtained data through complex processing. Complex processing of signals from various information channels can be carried out both at the detection stage and at the coordinate measurement stage. Moreover, it is most in demand at the detection stage due to the complexity of the detection and recognition task. The number of publications in this area is constantly increasing, and attention is also being paid to complex systems built using various physical sensors. However, the efficiency of systems with complex signal processing in practice is insufficient. The article is devoted to the analysis of the capabilities of complex systems with the processing of multimode information received from each of the channels used, as well as the development of new, more effective methods for integrating radar, optical, infrared, and acoustic channels of complex systems for detecting UAVs and determining their coordinates.
