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.

Routing tensor model with providing multimedia quality is proposed. The novelty of the proposed model lies in providing a given level of Quality of Experience regarding the multimedia quality indicator. Due to implementation of the tensornetwork analysis functional, it was possible to provide an analytical calculation of key parameters that influence the multimedia quality level: packet loss probabilities for audio and video flows, as well as the average end-to-end packet delay for the same flows transmitted within the multimedia session. The possibility of analytical and interconnected calculation of these QoS indicators allows to control the impact of desynchronization in time during delivery processes of packets of audio and video flows on multimedia quality, which is significant in the practical implementation of the proposed routing model.

Existing approaches to testing pseudorandom sequences, their advantages and disadvantages are considered. It is revealed that for sequences of length up to 100 bits there are not enough existing statistical packets. The available techniques show low flexibility and versatility in the means of finding hidden patterns in the data. Perspective direction of research – static testing of sequences using n-dimensional statistics is considered. To solve this problem, it is suggested to use algorithms based on multidimensional statistics. In the work, formulas are given and theorem for testing sequences for randomness, using two or three-dimensional statistics that can be used for small and medium-sized sequences is formulated. The new technique of PRS testing is proposed in the paper, and several criteria for testing bit sequence of small length are considered, which, in comparison with one-dimensional statistics, gives a more accurate result.

The algebraic approach to the formation of large ensembles of discrete signals with a multilevel correlation function, which is based on the section of cyclic orbits of group codes, is investigated. The number and magnitude of the side lobe levels of the correlation function of the sequences being formed, as well as the power of the ensemble of signals, are determined by the distance and structural properties of the polynomial rings over the final fields. Proposals are being developed for the hardware implementation of discrete-signal-generating devices with a multi-level correlation function using a chain of shift registers with linear feedback.
