Signal manifolds for antenna array of a primary surveillance radar Shejbal Tomas

The history of radar dates to the end of the 19th century in Germany, where Heinrich Hertz showed that electromagnetic waves reflect from conductive objects. The first demonstration of the radar principle was shown in 1904 in Cologne, Germany. Since this time, radars have been massively developed, mainly during Word War II. Nowadays radars for civil and military purposes are used in many different applications on the ground, sea, and in the air. The book deals with the part of the antenna which is used for ground based primary surveillance radar (PSR). The book focuses on synthesis methods for a vertical radiation pattern of a PSR antenna and design of signal distributions of the transmitter, control signal, as well as 1st and 2nd local oscillator. The book can be helpful to engineers who can find theoretical information related to antenna array synthesis, homogeneous lines, power dividers and distribution networks of the antenna as basic information about radar technology. Power divider simulation, measurement and other practical information can be found in this book as well.
