Methodology Aspects for Radio Receivers Development of Technical Monitoring Equipment

Within the framework of this article, a methodical approach to the development of radio monitoring receivers with high technical characteristics for assessing the parameters and current state of radio signal sources is outlined. One of the tasks of radio monitoring is to provide guaranteed detection of signals with modern types of modulation and various types of multiple access in a wide range of received signal powers. This task is divided into the following tasks: radio detection, estimation of signal parameters, as well as restoration and analysis of transmitted information. When solving the latter type of problems, the problem of determining the location of the source of information can also be solved. The listed tasks are proposed to be solved on the basis of the analysis of the parameters of the received signals. The latter largely depend on the quality of the radio receivers of the control system, especially when solving the problem of radio engineering analysis, when the parameters of the received signal are determined. At the same time, the work of modern technical means of monitoring is carried out in modes as close as possible to real time. This is due to the fact that modern radio electronic devices use various methods of noise protection, masking and encryption, which include fast and unpredictable tuning of the operating frequency, the use of a synthesized radiation pattern with the output of the minimum radiation in the direction of the intended control means, adaptive adjustment of the radiation power, the use of pseudo-noise signals with a large base, etc. The paper considers methodology aspects for radio receivers development of technical monitoring equipment, stages of designing such systems, and also presents examples of the implementation of the proposed approach.
