Formulation of the problem. The development of information systems for collecting, processing and exchanging radar information occurs, on the one hand, in the direction of improving the technical characteristics of information processing facilities and data transmission facilities, on the other hand, in the direction of improving information processing algorithms and the structure of the information system. This article summarizes the possibilities for the development of information systems in the second direction.Purpose. Development of a variant of building an information system with a fully connected network structure and intended for the collection, processing and exchange of radar information.Results. The development, as a tool for building an information system of a network structure, is based on an integrated approach that provides for the use of an algorithm without branching solutions for information processing, a network semi-connected structure itself and network algorithms, a higher level than the level of collection and processing, for organizing functioning of information exchange in the network. The short processing time of information when entering it into the system makes it possible to create a dynamic array of homogeneous radar data, updated when radar information arrives from sources.Practical significance. Information systems, wholly or partly built on the basis of such an integrated approach, are applicable in areas such as air traffic control systems; multi-beam and multi-range radars (ornithological, meteo, etc.), radars for security complexes, incoherent spatially-separated radar information sources, combined into a system (for example, for studying the ionosphere).

Problem statement. A rank algorithm for selecting radio emission modes for operation in conditions of heterogeneity of sources and complex interference conditions, including the possible presence of mutual interference, is synthesized.Objective. The synthesis purpose is to ensure the independence of mode recognition from particular features of radio emission observation. Algorithm input is the primary signal processing result that includes such estimations as pulses durability, frequency and amplitude dynamics, and absolute variations. Primary decision statistics are formed using these values: observable signal base and relation variations of frequency and amplitude. Secondary statistics are formed based on primary ones using median and recursive or maximum and recursive smoothing. Each of the decision statistics in the multi-threshold procedure is transformed into a row of ranks, the size of which corresponds to the number of recognized modes. In aggregate, these lines form a ranking table (matrix) with colons representing recognized modes’ discrete descriptions. Fluent observation processing includes rank formation for used decision statistics. Mode recognition is performed either following a ranking table or using an additional voting procedure 2/3. An alternative approach consists of constructing the Manhattan mismatch metric of the current and reference ranks and making a decision on the criterion of the minimum mismatch metric.Results. Mode recognition performed on results of this comparison using unbalance metrics minimum criterion. Thresholds in frames of the ranking procedure are formed heuristically at ranking table formation. They are then used at fluent rank formation for observable modes. The performed numerical experiment shows that maximal and recursive filtration provides an errorless selection of all observable modes. This filtration represents the composition of maximum selection in sliding window and subsequent recursive first-order filtration. An additional advantage of this filtration is a simpler maximum selection in comparison with the median one. In perspective, it can provide increased operating speed.Practical implications. Performed consideration shows that rank selection is worthwhile at the observation of heterogeneous irradiation sources. Algorithm strength is decision simplicity in a complex situation. Additional algorithm advantage is the possibility of extending alternative irradiation modes and, hence, for more representative data sets.

Formulation of the problem. The completeness of the characteristics of one of the most serious threats to the security of information today – its leakage through the transient electromagnetic pulse emanation standard (TEMPEST) from computer equipment (CE) is determined not only by the number of detectable signs of leakage but also by several other parameters characterizing the dynamics of the implementation of such a threat. The established patterns in the scenarios of violators’ actions associated with the use of technical reconnaissance equipment (TRQ) to intercept informative TEMPEST signals from computer equipment made it possible to form a model of all possible options for using TRQ to obtain confidential information processed by computer equipment. The proposed model provides the implementation of the methodological principles of the recognition theory for a more complete characterization of threats of information leakage through the channels of spurious electromagnetic radiation and interference from CE in the process of their detection.Objective. Development of methodological grounds for presenting signs of the violator’s implementation of certain functions associated with the use of technical reconnaissance equipment to intercept informative signals of spurious electromagnetic radiation and interference from computer equipment as signs that identify the most significant conditions for the recognition and prevention of such threats.Results. Methodological solutions for the identification of three states significant for the prevention of threats are given based on the structuring of the functional representation of the intruder’s actions to implement such threats.

The completeness of the characteristics of one of the most serious threats to the security of information today – its leakage through the transient electromagnetic pulse emanation standard (TEMPEST) from computer equipment (CE) is determined not only by the number of detectable signs of leakage but also by several other parameters characterizing the dynamics of the implementation of such a threat. The established patterns in the scenarios of violators’ actions associated with the use of technical reconnaissance equipment (TRQ) to intercept informative TEMPEST signals from computer equipment made it possible to form a model of all possible options for using TRQ to obtain confidential information processed by computer equipment. The proposed model provides the implementation of the methodological principles of the recognition theory for a more complete characterization of threats of information leakage through the channels of spurious electromagnetic radiation and interference from CE in the process of their detection.Objective. Development of methodological grounds for presenting signs of the violator’s implementation of certain functions associated with the use of technical reconnaissance equipment to intercept informative signals of spurious electromagnetic radiation and interference from computer equipment as signs that identify the most significant conditions for the recognition and prevention of such threats.Results. Methodological solutions for the identification of three states significant for the prevention of threats are given based on the structuring of the functional representation of the intruder’s actions to implement such threats.

Problem statement. The compensation problem of the amplitude error occurring when modeling radar targets using matrix simulators is considered. The relations that reveal the concept of this error are given. The example shows that the amplitude of the simulated echo signal differs from the amplitude of the real one.Objective. Justification of a method for correcting the amplitude error observed when simulating echo signals from radar targets using emitter matrices.Results. It is shown that when the scanning radiation pattern is oriented normal to the matrix base, the amplitude of the simulated echo signal does not depend on the angular target position. Based on this, a method was proposed to eliminate the error through pre-distortion of the echo signal amplitude. The ratio for calculating the predistortion multiplier coefficient is obtained. In the framework of a numerical experiment, the amplitude of the simulated echo signal was estimated for various angular positions of the scanning radiation pattern without taking into account predistortion and with predistortion. The experimental results confirmed the correction effectiveness.Practical implications. The results obtained allow increasing the adequacy of modeling radar objects by matrix simulators by ensuring that the amplitude of the simulated echo signal corresponds to the amplitude of the real one.
