THE ANALYSIS OF EXPERT SYSTEM FOR ADAPTING DECISIONS FOR DETERMINING THE TYPE OF RADIO RESPONSE SOURCES

Abstract

In this article, the authors of research described the sources of radio radiation and explained the complexity of identifying sources of radioelectronic radiation under a priori uncertainty. Authors of the article state, that the source of radio-electron radiation can be identified by a set of parameters of its signal. It is established that the informational nature of the signal source of radio emission for the devices of radio monitoring depends on how reliable this signal is detected and how accurately (precisely) its parameters are determined, which are useful days of radio monitoring of the message or value. Because signal tracking always takes place against a background of different kinds of interference, the fact of detecting a signal, as well as errors in measuring signal parameters and selecting messages are always random. The problem of determining the type of signal, and therefore the source, which it emits, is partially solved by the preliminary analysis of the ether on the hearing conducted by the operators of radiomonitoring. This makes it possible not to distract from non-informative signals belonging to sources of radio-electronic radiation that are not showing interest to radio monitoring, to shorten the search time for sources of radio-electronic radiation and to minimize the cost of depreciation of equipment. The disadvantage of this method is the necessity to have a sufficient number of trained operators and to constantly increase their training. Was given that the preparation of one operator to a professional level can last 6-12 months, it is very difficult to provide data requirements. Therefore, in the given article it is suggested to analyze the parameters of sources of radio-electronic radiation on a set of parameters of sources signals of radio-electron radiation with the help of expert decision support system concerning determination of sources parameters of radio-electronic radiation. In the article, the authors proposed an expert system for determining the parameters of sources of radio-electronic radiation using a database management system. Unlike machine programs that use procedural analysis, expert systems solve problems in a narrow subject area (specific field of expertise) based on deductive considerations. Such systems are often able to find solutions that are unstructured and poorly defined. They cope with the lack of structuring by involving heuristics, that is, the rules described in accordance with the experience of using the equipment, which may be useful in those situations where the lack of necessary knowledge or time eliminates the possibility of complete analysis.
