The aperture synthesis systems allow imaging with high spatial resolution. These images are important for solving problems of Earth remote sensing. One of the promising directions for development of such systems is the transition to UWB spatiotemporal signals processing. This raises a number of difficulties in the physical interpretation of the main UWB radio systems characteristics due to the fact that the classical definitions were introduced with regard to the narrowband systems description. Thus, there is a need for additional research and further definition of UWB systems characteristics and parameters. Among these characteristics is the spatial-spectral sensitivity domain, which, along with the uncertainty function, determines the quality of the radio system. Unlike in radio systems for narrowband signals processing, for systems with UWB signal processing the spectral sensitivity domain depends on both temporal and spatial frequencies. Analysis of this area is complicated by the fact that the temporal and spatial frequencies in the UWB system are not divided. In this work, the physical essence of the spatial-spectral sensitivity domain was studied and it was shown how its analysis will allow to develop requirements for the choice of antenna system geometry and to justify the expediency of using the working frequency band.

A post-classification processing technique for multi-channel images that includes three stages is proposed. The purpose of the first stage is to correct decisions of pixel-by-pixel classifiers based on estimates of classes’ posterior probabilities. At the second stage, a logical convolution of the classification layers is performed which makes it possible to select the most probable class. At the final stage, local spatial filtering of pre-segmented image is done which is performed in the neighborhood of detected segments’ edges. The post-classification processing effectiveness is verified for satellite images. It is demonstrated that the proposed post-classification processing procedure can significantly increase the probability of recognizing poorly distinguishable classes and improve overall accuracy of image classification.

The mathematical definition of the optimal choice problem for software package for an enterprise information system is considered. The problem of the optimal software package choice is a mathematical model of combinatorial optimization on a set of combinations. The algorithm for solving this problem is presented for finding the minimum value of the target function considering additional linear constraints. This method makes it possible to significantly simplify the finding procedure of the optimal solution, since inequalities in the growth of constraints allow us to immediately determine whether a point in the set of combinations will be a support solution or not. In the positive case, the support solution is improved, taking into account the properties of many combinations when directly checking the growth of the target function. The algorithm and its realization are demonstrated by a numerical example. The proposed mathematical model and solution algorithm can be used for a similar class of problems that are modeled by optimization models, where the set of feasible solutions is presented in the many combinations form.

Cybercriminals and nation-state hackers are investing heavily in strategies devised to disrupt critical infrastructure systems. Nearly one out of two Industrial Control System (ICS) computers in the energy sector had been impacted by malicious cyber activity in 2018. With threats increasing and attack vectors expanding, critical infrastructure sectors like energy need to implement innovative technology to ensure Critical Infrastructure Protection. This study reviewed blockchain research published between 2015 and 2019 in order to examine the development of blockchain, evaluate current applications of blockchain in the energy sector, and propose additional opportunities for the application of blockchain technology. Quantitative analysis revealed that blockchain-based cybersecurity research and application in the energy sector is increasing at an annual average growth rate of 169% since 2015 with intensified focus on Internet of Things (IoT) and Smart Grid infrastructures. Computed projections forecast a continued increase in the research and application of IoT and Smart Grids. Calculations indicate that nearly 50% of the new research will be in blockchain-based cybersecurity solutions such as cryptographic communications and secure email. Qualitative analysis indicates potential for blockchain- based cybersecurity solutions to provide enhanced Critical Infrastructure Protection in those sectors against pervasive phishing and social engineering threats.
