This book highlights the synthesis of polarization selection system in the background of passive noise formed by reflections from space-distributed targets. This synthesis is fulfilled as close as possible to its ideal configuration in terms of maximal signal-to-noise ratio for the matched load of radar station antenna system. It presents a new approach to radar system resolution enhancement based on the development of mathematical model for radiometric receivers with mono-pulse antenna systems, as well as creation of a new algorithm that allows increasing angular resolution during the object’s search and tracking due to special signal processing.

The presence of randomly oriented, nonspherical particles in the atmosphere results in the appearance of a depolarized component of the radar signal, that is, the echo signal. When there is sufficient radar sensitivity, this effect can be used to discriminate between the liquid phase (spherical droplets) and the crystalline phase in clouds. To realize certain theoretically observed possibilities, an apparatus was set up on the radar laboratory, which permitted the transmission of both linearly and circularly or elliptically polarized waves. Theoretical analysis and experimental measurements made with this equipment give reason to expect that polarization characteristics can be used to obtain valuable information on the structure and variation of the parameters of meteorological objects.

Methods of measuring the polarization parameters of electromagnetic waves are described and compared. Five methods are presented: polarization diagram method; compensation method; method of decomposing the wave into orthogonally polarized components; method of several antennas; and modulation method. Components and units of radars with polarization selection of signals are discussed.

Sidelobe contributions to a radar signal's polarization may distort the polarization of clutter originating in the mainbeam. To assure that radar clutter polarization measurements are accurate and that polarization nulling algorithms under consideration would work properly, it is necessary to analyze the contributions of antenna sidelobe clutter to signal polarization. This report considers two bistatic radar configurations over homogeneous terrain. The terrain is represented by the two-scale-of-roughness bistatic scattering model. Two antenna models are used, one a square aperture, and the other a simple approximation to a circular aperture with adjustable sidelobe levels. The results for the square aperture show a small change in the signal polarization from the mainbeam-only value when the sidelobes are added in. For the adjustable sidelobe level antenna the sidelobe corruption is small until the uniform sidelobe level reaches -20 dB. Bistatic radar, Polarization, Sidelobe clutter.

This book analyzes various properties and structures of ice from the point of view to solve problems in civil aviation. The Arctic zone of the Russian Federation, together with large territories of Siberia and the Far East, is a zone, that is insufficiently provided with ground navigation facilities, as well as platforms and airfields for landing aircraft, including in the event of unpredictable situations. However, most of this area, especially in winter, is covered with ice, which can be used to solve this problem. The possibility of using ice sheets for the construction of airfields or the location of ground-based flight support facilities requires careful study and analysis. This book is devoted to the study of the properties and structure of ice, with a view for use in civil aviation to construct ice airfields and the placement of ground-based flight support facilities.

This book presents a methodology for assessing environmental safety in civil aviation. The methodology allows the comparison of different technological processes and evaluates their impact on the environment. At the same time, the medical and demographic indicators for ecologically unfavorable territories are compared with similar indicators in the control (background) territories in the same climatic and geographical zones. This book contains methodological recommendations for the creation of the system for ecology safety in the organizational structures of civil aviation. This book is useful to a wide audience—students of aviation, lecturers, as well as specialists in the field of ecology and those involved in ensuring the necessary ecology requirements at aviation enterprises.
