The article considers the monitoring and diagnostic system of a combined radio engineering system fromthe perspective of the theory of complex systems. Concrete examples of combined radio systems are given, which requirethe development of unified monitoring and diagnostic systems. The functioning of such the combined radio engineeringsystem as a mobile digital troposcatter-radiorelay station requires taking into account the features of the multipathtroposcatter channel with fading. Therefore, the unified monitoring and diagnostic system should include an simulator of amultipath channel with fading. Such the unified system of monitoring and diagnostics itself becomes complex system.From the other side, the use of a fading multipath channel simulator leads to a highly branched structure. Reducing thebranch points of the computational process of such a complex structure allows using a simulator that is built into the monitoringand diagnostic system without compromising the quality of information transfer. Also, the construction of a unifiedmonitoring and diagnostic system should take into account control over resource efficiency. The decomposition method iscompared with the Bayesian approach in solving the problem of the calculation procedure. It is noted that the Bayesianapproach is possible with a sufficient amount of a priori information. A specific calculation of reducing the branch pointsof a computational procedure by applying the decomposition method is presented. When changing one parameter, the degreeof branching decreases by 1.5 times. The article shows the directions of perspective scientific and technical developments,such as: combined telecommunication platforms combining various types of communications radio relay andtroposcatter, troposcatter and space; radar detection of targets, their recognition, tracking and guidance; combined radionavigationand radar air traffic control systems.Downloads
