Course detail

Radars and Navigation Systems

FEKT-NRARAcad. year: 2019/2020

Students will be introduced to the definition of the radiolocation, and elementary types of radars and their characteristics. Characteristics of targets, radar equation, and radiation patterns of radar antennas are studied in the next part of course. Students familiarize with effects of the electromagnetic wave propagation on the radar measurement, methods of space scanning, and radar signal processing. Technology of pulse and continuous radars and their block diagrams and characteristics will be described in the follow part. Students will be introduced to applications of modern radar systems - surveillance radars, over the horizon radars, collision avoidance radars, and ground-penetrating radars in the conclusion of training concerning on radar systems. Fundamentals of navigation theory, instruments and calculations are lectured in the beginning of navigation theory part of course. Students will be initiated to AM, PM, FM and IM navigation 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 to global navigation satellite systems - GPS-NAVSTAR, GALILEO, GLONASS, BEIDOU, QZSS. The application satellite navigation systems and architectures of GNSS receivers will be presented in the final part of course. Course is supplemented by laboratory a computer practices and field trip to ATC department in Brno Airport or to radar companies.
