The synthesis of a single-channel broadband device for receiving and primary processing of radio signals that employs the pulse compression technique is presented given the case where its input signals are received in conditions of their structural-parametric a priori uncertainty. The synthesis was carried out based on the mathematical apparatus of the theory of statistical decisions and on the discrete signal representation in the time-frequency domain. The results of prototyping and experimental studies concerning the receiver that was synthesized in accordance with the structural-functional diagram on the basis of spectrum analyzer with pulse compression technique (SAPCT) are briefly presented. An experiment is described that allowed us to verify the possibilities of obtaining the Fourier transform with regard to the elements of input signals, as well as possibilities of detecting and measuring the frequency-time parameters of these signals. These parameters allow us to figure out the structure and characteristics of input signal bursts [6].

On the basis of formal systems the problem of creating knowledge models for the task of recognition of radio-emitting objects and their states in terms of a priori uncertainty is considered. As a formal system the first order predicate calculus extended by aletic modal logic operators is used. The mechanism of logical inference is developed using a modified method of resolutions. The examples of construction of knowledge models, implemented with the use of expert system are given and experimental studies, which confirmed their effectiveness and high reliability of the results achieved, are carried out.

The present study investigates electromagnetic plane wave diffraction by a strip with two different surface impedances on both sides. On the strip, the Leontovich boundary conditions are satisfied on each surface. Then, the solution is obtained by the analytical-numerical method called orthogonal polynomials. The numerical results are analyzed with the fractional derivative method. The paper answers how to build up the mathematical background of the problem and provides near electric field distribution, and total radar cross-section for different cases.

The paper deals with issues related to the technical possibilities of using modern ultra-wideband ground penetrating radar (GPR) for detecting hidden subsurface defects. Some issues related to the use of ground penetrating radars were also considered in earlier works of the authors, however, in this publication, new results obtained by the authors on the roads of Ukraine are discussed, and the development of this topic is also proposed. The corresponding proposals are based both on the achievements of modern radiophysics and on successes in related fields of science, both technical and applied. The relevance of this topic is evidenced by a significant number of publications, both those that have already become classics and modern ones. The introduction contains an overview of remote sensing methods and a brief analysis of the possibilities of using GPR for road surveys. The conclusion contains an analysis of some of the results obtained in the work and related further developments in this direction.

In this work, we study the surface electromagnetic waves propagating along the self-complementary metasurface. We propose a way to excite the surface waves of the necessary polarization by using the TE-TM degeneracy property of the self-complementary metasurface. In particular, we demonstrate the excitation of surface waves with linear horizontal, vertical and diagonal as well as circular polarizations. The proposed technique opens new possibilities for the in-plane signal transferring and transformation.

The paper discusses applications of the wave analog of the Smith-Purcell effect in microwave energy compressors. It is demonstrated that both energy accumulation stage, and switching and release of accumulated energy could benefit from the realization of this effect. A whole new family of compressors featuring the wave analog of the Smith-Purcell effect is establishing, and a couple of novel compressors' designs are presented as examples in this paper.

Numerical simulation of non-uniform profile retrieval of rain intensity was performed for operating wavelengths 0.82 and 3.2 cm and for different values of measurement errors of received powers and total attenuation. Retrieval method uses the Tikhonov regularization for solution of the integral equation of scattering and inverse iteration procedure for taking into account the signal attenuation. It is shown that proposed method provides the acceptable retrieval error (maximum is less than 40 %) for intensity more than 3 mm/h.

The perspective direction for increasing the signal constructions secrecy in radio communication systems. One of the solutions to the problem of information security increase at the first level of the OSI reference model [1] is the use of various spectrum-spreading methods of the information signal, such as: frequency hopping spread spectrum (FHSS) [2], direct Sequence Spread Spectrum (DSSS) [3]. This allows to solve problems of ensuring the energy secrecy of signal constructions. Another important indicator for ensuring the information protection from unauthorized access is the strong signal constructions structural secrecy. This indicator should resist measures that are aimed at detection the form of signal structures, if the enemy has solved the problem of detecting the fact of messages transmission and interception. For increasing the structural secrecy, it is proposed to use timer signal constructions (TSC). TSC are non-positional signals. Based on TSC on the given time interval, it is possible to create larger number of signal constructions than for positional signals. In works [4], [5] was given an assessment of the structural secrecy of TSC, which made it possible to conclude that it is expedient to use them in noise-protected communication systems. So, in this paper perspective approach for the formation of broadband signal-code constructions based on various signal spectrum-spreading methods is proposed. Proposed method for forming TSC based on combined technology of FHSS and DSSS application. Its effectiveness plane to evaluate in the course of further research
