The necessity to find a rational way of creating a database regarding the sighting surface taking into consideration the features of construction and functioning of correlation-extreme navigation systems (CENS) of aerial mobile robots (MR), including in particular the conditions of flexible change of flight assignment, is shown in the article. It is proposed to use invariants, which have been obtained based on a correlation analysis of the scene according to the brightness index with the subsequent and allowing to form selective images, as a database information content. The results of the evaluation of the quality of formed selective reference image (RI) for scenes with various object impletion under conditions of limitations in time and number of calculations are given

This paper proposes an algorithm for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems, taking into consideration the operational patterns of such systems. Underlying this algorithm is the combination of survivability assessment methods and reliability assessment methods. Such an arrangement aimed to improve the efficiency of the application of these methods and reduce uncertainty in the calculations. The results from calculating an example of the application of a procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems have been analyzed. The analysis of the results shows that the set task is fulfilled, in particular the specified probability of trouble-free functioning of a reconnaissance-firing system, with a combined type of redundancy. Moreover, it implies giving preference to passive redundancy, using active one only to critical elements – individual functional elements of the control subsystem. The advantage of a mixed type of redundancy over a passive redundancy is 28 %. In addition, it has been established that the multiplicity of redundancy, for accepted conditions, should not be lower than 2. A procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems has been devised, taking into consideration the operational patterns of such systems. The specified procedure includes an algorithm, as well as methods for assessing survivability and methods for assessing the reliability of functioning. This procedure was tested for feasibility by considering an example of justifying the type and volume of redundant structural and functional elements of reconnaissance-firing systems that produced an adequate result. The result has been confirmed by the practical application of reconnaissance-firing systems in recent armed conflicts

The functionality and purpose of combat wheeled vehicles (CWV) models are determined by both the requirements of the armed forces and the financial and technical capabilities of military equipment manufacturers. This leads to a discrepancy between the technical characteristics of the CWV model and its combat purpose. For the classification of CWV, an approach is proposed that consists of using generalized indicators that characterize the combat properties of CWV models, which allows establishing a correspondence between the technical characteristics of CWV models and their functional purpose, provides an opportunity to develop rational protection options and to justify specific technical solutions to increase the level of survivability of CWV models within groups.
