Course detail

Radars and Navigation Systems

FEKT-LRARAcad. year: 2009/2010

Students will be introduced to the definition of the radiolocation, and elementary types of radars and their characteristics. Characteristics of radar's targets, radar equation, and radiation patterns of radar's antennas are studied in the next part of course. Students familiarize with effects of the electromagnetic wave propagation on the radar operation, methods of space scanning, display and processing of a radar information too. The pulse and continuous radars, the flow diagrams and characteristics will be described in the follow part. Important question in modern radar systems is moving target indication and underirable responses suppression. Students will be introduced to the latest feature of a radar systems - the over the horizon radar, the car to car collision radar, the terrain ground collision avoidance radar in the conclusion of training concerning radiolocation theory and application. The elementary navigation theory, instruments, and calculations are lectured in the beginning of navigation theory. Students will be initiated into basic of AM, PM, FM, and IM radionavigation systems. The air navigation services of a long distance flight, instrument landing, and VOR, ILS, MLS, and DME systems are indivisible part of course. The last part of course is devoted satellite navigation systems, as GPS-NAVSTAR, differential methods, and GPS applications. GNSS1, GNSS2, and GALILEO projects will be described in conclusion. The application satellite navigation systems in the civil air navigation services. Course is supplemented by practical mmeasurement in terrain and visitation in Center of Air Navigation Services on ČSA Brno Airport.
