Abstract

The intelligence system is a multilevel recognition system. One of the top priorities of the intelligence system for intelligence objects is the task of recognizing them. For example, in an electronic reconnaissance system, the type of radio and radar station is a sign of determining the operational and tactical affiliation of a radio network or radio system, while determining the type of radio and radio station is one of the tasks of recognition. The recognition process is defined as one of the types of classification. The principle of recognition as a process of information processing is the division of information into a posteriori and a priori. Recognition is the process of comparing the obtained intelligence data on a certain intelligence object (a posteriori information) with the data, which consists in the description of all intelligence objects (a priori information) with the help of intelligence features, to determine the affiliation of the intelligence object. A posteriori data on the object of reconnaissance is compared with a priori information using recognition algorithms. Recognition is used to establish the operational and tactical affiliation of individual electronic means, networks, communication nodes, command posts, as well as to take into account the impact of enemy resistance. Some processes can be both processing tasks, such as systematization of information, data, features. At the moment, in a number of works, attempts are being made to expand the feature space and improve the scientific and methodological apparatus of recognition. These works are aimed at improving system performance, in particular - the probability of correct recognition. In order to determine how much this value has changed, depending on various factors, methods of mathematical modeling of the system, as well as laboratory and field experiments are used. The use of the latter is associated with certain difficulties, especially when it comes to a complex dynamic system of intelligence on the activities of foreign states in space, the means of measurement of which have a wide geography of location and differ in various features of operation. To assess the main indicators of the recognition system and ensure the possibility of optimal choice of means of measuring the parameters of the reconnaissance objects, it is proposed to develop a model of system operation. A mathematical model of the functioning of the recognition system is proposed. Application of the considered model will allow to solve the problems connected with construction of systems of recognition and definition of necessary quantity of signs.
