Radar

Lecturer:

Tutor:

Supervisor:

Department of Radioelectronics

Synopsis:

Student will study principles of active (primary and secondary) radars and passive radars and various radar types. Erudition of signals and systems and theory of antennas and electromagnetic wave propagation in the land atmosphere is supposed. Obtained knowledge is useful in radio industry and development, in air traffic control and operation, meteorology, geodesy and cartography.
