Studying the inherent features of operation is a preventive measure to prevent premature failure of the object, in the technical sense. Practice indicates that the best means for determining the properties of objects is a natural experiment, that is, a study of the properties and condition of the object under appropriate conditions and operating factors of influence.\u0000However, in most cases, a full-scale experiment is not possible or appropriate. Some tests may be close to extreme conditions, may proceed so violently that accidents and destruction of components or the entire object are possible. That is why process modeling and control calculations are used to determine individual reliability standards. At the same time, reliability indicators (RP) are usually carried out for unique objects, the calculation is based on the RP of similar elements (objects as a whole) and, if necessary, these indicators are extrapolated.\u0000If the control calculations are very cumbersome or significantly distort the actual indicators, then probabilistic modeling is carried out on computers (computers) using test data of individual elements or on the operational data of prototypes of the necessary objects.\u0000A prerequisite for various types of simulations should be the construction of operator models for depicting the processes that accompany the actual life cycle of the object, as a result of which there is a clear understanding of the factor stages of influence on the technical condition, failure forecasting, prevention of the appearance of negative or critical factors affecting the survivability of the object in in turn, the analysis of the need for technical maintenance, its sequence, volumes or even expediency.\u0000Keywords: operational model, failure, maintenance, operation of combat vehicles, technical condition, restoration.","PeriodicalId":421105,"journal":{"name":"Collection of scientific works of Odesa Military Academy","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132615052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prospective direction of overcoming parametric a priori uncertainty is affiliated with the prior learning procedure. As a result of the training, sufficient statistics of likelihood ratios are formed, which are used in decision-making. The asymptotic optimality of adaptive systems with alternative benchmarks, one of which is peculiar to the class of radio structures with an adaptive antenna array and the other with an adaptive interference compensator, is studied subjectively with unclassified training sampling. The optimality of the system is determined by the criterion of maximum signal-to-interference ratio. The energy parameter representing the signal-to-interference ratio at the output of adaptive radio systems with a generalized reference was chosen as an indicator of optimality. As a result of the research, analytical expressions for the estimation and comparative analysis of energy losses at the output of adaptive systems with different standards under conditions of classified and unclassified learning were obtained. The invariance of the system with an adaptive antenna array to any type of training with preservation of the asymptotic properties of the radio system in the situation with a finite size of the training sample is proved. This feature is considered as a basis for factorization of the transfer function of the adaptive system. This makes it possible to form an optimal hierarchical algorithm for compensation of combined passive and active interference, as well as active interference with an arbitrary spatial power spectrum. The obligatory classification of a training sample of observations for radio engineering systems with an adaptive interference compensator under conditions of signal-interference a priori uncertainty is substantiated.\u0000Keywords: asymptotic optimality, adaptive system, alternative benchmark, unclassified training sample, correlation matrix of observations, energy index.","PeriodicalId":421105,"journal":{"name":"Collection of scientific works of Odesa Military Academy","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122737682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was established that the process of processing information that enters the information-controlled system in digital form from various sensors involves the calculation of discrete convolutions of matrices of relevant operators and arrays of initial data. This process includes procedures for forming an array of responses to the observed information flow, an array of responses to the restored (restored) information flow, and forming conditions for restoration (restoration) of the observed information flow. The approach to assessing the quality of digital information processing in terms of determining subjective and objective assessments and methods of obtaining them is analyzed. The basis of these methods is the procedure of direct inversion of the estimated correlation matrix of random realizations of the observed multidimensional information process. Systems with an inverse operator for processing a multidimensional information array are quite sensitive to destabilizing influences: to random perturbations of the coefficients of the recovery (processing) operator and internal noise of the system along with internal system perturbations. The need to take into account destabilizing influences in the process of processing digital information in the car's information-controlled system necessitates the development of a general methodology for studying the influence of destabilizing factors on the quality of image processing.\u0000Based on the application of inverse synthesis methods, analytical expressions for criterion quality indicators of digital image processing are proposed, which are not limited to the upper limit of quality assessment and allow analytical evaluation and quantitative determination of the quality level of discrete images restored by direct inversion at the stage of system synthesis.\u0000Keywords: car, information-controlled system, image, restoration, restoration operator, criterion indicators, multisensory information, quality of information processing. internal noise, destabilizing factors.","PeriodicalId":421105,"journal":{"name":"Collection of scientific works of Odesa Military Academy","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127111059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem of choosing the convergence step of gradient methods is non-trivial due to the lack of a priori information about the target function which is minimized (maximized). A fixed adaptation step does not guarantee stable convergence and stability of the adaptation process.\u0000It is proposed to replace the constant constant of the adaptation step with a variable whose elements depend on the contrast of the spectral distribution of the correlation matrix of observation, and to increase the speed of convergence of these processes, to apply the second-order gradient method.\u0000As a result of the synthesis, a generalized analytical form of the quasi-Newton algorithm for an arbitrary step of adaptation for adaptive RTS with an antenna array was obtained. Quasi-Newtonian algorithms for stabilizing the dynamic parameters of the adaptation process of the adaptive interference compensator (AIC) and AAR have been synthesized, which are the best among the algorithms of approximate calculations.\u0000The use of these algorithms is advisable in the case of limited computing resources. The conducted study of the efficiency of the quasi-Newtonian algorithm of parametric adaptation for AIC and AAR according to the signal/(interference+noise) ratio criterion, which is achieved at the RTS output, maintains its stability in any of the considered situations, regardless of the influence of arbitrary intensity ANI.\u0000Keywords: adaptation, adaptive antenna array, adaptive interference compensator, interference, signal/(interference+noise), quasi-Newton, gradient method.","PeriodicalId":421105,"journal":{"name":"Collection of scientific works of Odesa Military Academy","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132277349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
