Abstract
It is known that the requirements for the efficiency and quality of carrying out operations for controlling the technical condition of complex systems are increasing due to the transfer of systems and objects to operation in a state of technical condition. In the article the presence in the practice of controlling the technical condition of complex systems of contradiction is considered, namely, the provision of the given reliability of information about the technical state of the radio navigation complexes of the traffic control of water transport means requires an increase in the volume and accuracy of measurements in evaluating their characteristics on the one hand, and on the other - the lack of methods for automating processes the synthesis of the measurement signals and processing feedback on them for this. Traditional measurement signals for monitoring the technical condition of radio systems are sinusoidal oscillations. However, this approach requires a considerable workload of control and leads to a reduction in the efficiency of its conduct due to the need to introduce inertial blocks to increase impedance protection. Avoid this disadvantage is possible due to the use of multi-frequency signals with a normalized spectrum - polyharmonic signals. They represent the sum of a certain number of useful harmonics, modulated signals with a normalized spectrum and different forms of binary signals. Therefore, the actual scientific problem is the development of methods of synthesis of polar harmonic measuring signals and processing of reviews on them to increase the reliability and efficiency of automated control of the technical condition of radio systems. According to the results of the analysis of measuring signals and known methods for the synthesis of measuring signals, the results of the study of the subject area, which include the study of the methods of synthesis of measuring signals with the normalized spectrum, are proposed in order to improve the process of automated control of the technical state of radio systems. In addition, features of the experimental verification of the obtained theoretical results and the development of recommendations for their implementation for the automated control of the technical state of the radio navigation complexes for controlling the movement of water transport vehicles are presented
