CYCLIC THREE-STAGE PROCEDURE FOR SINGLE-CHANNEL DETECTION OF MOBILE RADIO SIGNALS IN THE FREQUENCY-TIME DOMAIN

In the context of a full-scale invasion and military operations for the independence of Ukraine, the issues of radio monitoring of radio emission sources of telecommunication networks and systems are gaining special attention and require fundamentally new approaches to the level of informatisation, technical implementation and increase of their efficiency.Today, technical means of radio interception, monitoring and direction finding in mobile radio networks are implemented in the form of software and hardware complexes, the most important performance indicators of which are speed, detection accuracy and reliability of recognition of mobile radio communication means with their information content. At the same time, these issues still remain problematic and require further development of methods and means for searching and detecting signals of mobile radio communication equipment in both frequency and time environments of telecommunication channels and their subsequent information processing.To address this issue, the authors propose a cyclic procedure for single-channel search for mobile radio signals with three stages of detection in the frequency-time domain and its mathematical model. It is shown that the use of a cyclic procedure for single-channel search for signals of mobile radio communication means with three stages of detection in the frequency-time domain will ensure high quality of radio monitoring and efficiency of estimation of spectral components of radio signals in terms of speed, detection accuracy and probability of recognition of mobile radio communication means with further determination of their information content.
