The relevance of the development and modernization of synchronization algorithms, which reduce the synchronization time of the quantum key distribution (QKD) system, while maintaining enhanced security against unauthorized access, is noted. The synchronization algorithm is described, where, to increase security from unauthorized access, quantum pulses are used as synchronizing signals. A quantitative assessment of the influence of the dispersion properties of a fiber-optic line on the efficiency of the two-stage single-photon synchronization algorithm of the autocompensation QKD system is given.

The article proposes a two-stage approach to solving the problem of the synthesis of a microstrip filter. It is shown that the two-stage design allows almost ten times to reduce the displacement of the attenuation characteristic arising due to the limitations of the synthesis method used for the design.

This paper presents the method of calculating the maximum usable frequency (MUF) and field strength of radio waves reflecting 2 times at the F2 ionosphere layer under inhomogeneous conditions of the ionosphere. The comparison between predicted and measured MUF has shown that the proposed method significantly increases the accuracy of calculation MUF. The results of calculating frequency dependence of the radio field strength have shown that the scattering of radio waves in the ionosphere leads to the possibility of receiving radio waves at frequencies exceeding the maximum usable frequencies.

The study of lenses when their sizes are units and tens of wavelengths. For the analysis of lenses in the specified range, it is proposed to use a high-frequency integral equation with the representation of the green function in both spherical and cylindrical representations. The focusing properties of lenses of different profiles are investigated.

The problems of representation of the signal model in distributed information-measuring systems are considered in this report. The features of stabilization of frequency of generators in the distributed information-measuring systems are considered on the basis of this model. The main problem is to account for condition of delay between the moment of signal formation and the moment of estimation of its frequency-time parameters. It is proposed to use a polynomial model of frequency change. The coefficients of frequency time dependence are determined from the condition of equality of the phases of the processed signal and the parameters of the signal generated with delay. The numerical results is presented in the report.

A model of calculation of polarization scattering matrices for objects of observation in a complete polarization basis in view of features of their motion was developed. Simulation of implementations of polarization scattering matrices for various classes of objects of observation was carried out. Plots of dependence of the angle between the symmetry axis of objects of observation and the sight line on the time of observation were presented. Simulation of the process of classification of objects of observation by polarization attributes with the use of the model of calculation of polarization scattering matrices was carried out. Based on obtained implementations of polarization scattering matrices, informativeness of various groups of polarization attributes was studied.

The article describes the method and process of designing a interdigital bandpass filter on two two-stage microstrip resonators. As a result of the design, thanks to the introduction of two steps of different widths into the resonator, it was possible to double the barrier band by suppressing the parasitic bandwidth in the vicinity of the third harmonic.
