Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
ought¿s A-7 Corsair II served the U.S. Navy for over over two decades, and flew with distinction during the Vietnam conflict. The subsonic A-7 was based on Chance Vought¿s supersonic F-8 Crusader. It boasted a heads-up display, an inertial navigation system, and other innovations. The plane entered service in 1966, and served in Vietnam in late 1967. Its performance was impressive. The USS Ranger¿s VA-147 flew over 1,400 sorties with the loss of only one aircraft. The Air Force purchased an advanced version, the A-7D, equipped with a more powerful engine. The plane later flew missions over Lebanon, Libya, Grenada, Panama, and Iraq. The last planes in U.S inventory were retired in 1991. Originally printed by the U.S. Navy and Vought, this handbook for the A-7 provides a fascinating glimpse inside the cockpit of this famous aircraft. Originally classified ¿restricted¿, the manual was recently declassified and is here reprinted in book form.
