Foundations for Innovative Application of Airborne Radars

Measuring the Water Surface Backscattering Signature and Wind

By: Alexey Nekrasov

The ‘wind vector’ – wind speed and direction – is a main meteorological quantity and relevant for air-sea exchange processes. This book explores the use of several airborne microwave instruments, some of which are part of standard aircraft equipment, in determining the local wind vector over water. This is worthwhile as local wind information is usually only available at measurements sites like weather stations and airports, and global wind information from satellites has very coarse resolution and poor temporal coverage – at most a few times daily. In his book, Nekrasov uses known results in a novel way and gives explicit and application-oriented descriptions how to additionally retrieve local wind information from standard airborne microwave instruments. The results presented here are highly valuable for flight operation above the sea (e.g., search-and-rescue) but also for complementing other measurements of atmospheric or oceanic parameters during research flights.

Stalingrad

City on Fire

By: Alexey Isaev

“A fresh look at what is perhaps the most famous battle of the Russo-German War from the Soviet perspective.” —The NYMAS Review Much has been written about the Battle of Stalingrad, the Soviet victory that turned the tide of the Second World War. Yet our knowledge and understanding continues to evolve, and this engrossing account by Alexey Isaev brings together previously unpublished Russian archive material—strategic directives and orders, after-action reports, and official records of all kinds—with the vivid recollections of soldiers who were there, on the front lines, reconstructing what happened in extraordinary new detail. The evidence leads him to question common assumptions about the conduct of the battle—about the use of tanks and mechanized forces, for instance, and the combat capability and tenacity of the defeated and surrounded German Sixth Army in the last weeks before it surrendered. His gripping narrative carries the reader through the course of the entire battle from the first small-scale encounters on the approaches to Stalingrad in July 1942, through the intense continuous fighting through the city, to the encirclement, the beating back of the relieving force, and the capitulation of the Sixth Army in February 1943. Military historian Alexey Isaev’s latest book, with maps and illustrations included, is an important contribution to the literature on this decisive battle. It offers a thought-provoking revised view of events for readers already familiar with the story, and a fascinating introduction for those coming to it for the first time.

The Fight for Influence

Russia in Central Asia

By: Alexey Malashenko

Russian influence in Central Asia is waning. Since attaining independence, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan have forged their own paths—building relationships with outside powers and throwing off the last vestiges of Soviet domination. But in many ways, Moscow still sees Central Asia through the lens of the Soviet Union, and it struggles to redefine Russian relations with the region. In The Fight for Influence, Alexey Malashenko offers a comprehensive analysis of Russian policies and prospects in Central Asia. It is clear that Russian policy in the formerly Soviet-controlled region is entering uncharted territory. But does Moscow understand the fundamental shifts under way? Malashenko argues that it is time for Russia to rethink its approach to Central Asia. Contents 1. Wasted Opportunities 2. Regional Instruments of Influence 3. Russia and Islam in Central Asia: Problems of Migration 4. Kazakhstan and Its Neighborhood 5. Kyrgyzstan—The Exception 6. Tajikistan: Authoritarian, Fragile, and Facing Difficult Challenges 7. Turkmenistan: No Longer Exotic, But Still Authoritarian 8. Uzbekistan: Is There a Potential for Change? Conclusion Who Challenges Russia in Central Asia?

Foundations for Innovative Application of Airborne Radars

Functionality Enhancement for Measuring the Water Surface Backscattering Signature and Wind

By: Alexey Nekrasov

This book discusses methods for measuring the water surface backscattering signature and estimating the near-surface wind vector over water using airborne radars, in addition to their standard application. Airborne FMCW demonstrator system, Doppler navigation system, airborne weather radar, airborne radar altimeter, and airborne precipitation radar are analyzed in order to be used for that purpose. The radars functionality is enhanced for their operation in a scatterometer mode. A circle flight and/or a rectilinear flight of an aircraft over the water surface is considered depending on the radar design features to perform measurements of the azimuth normalized radar cross section curve of the water surface and/or the near-surface wind speed and direction. Flight recommendations to perform measurements along with algorithms for measuring the water surface backscattering signature and for retrieval of the wind speed and direction over water are presented.
