RADAR and its Applications (original) (raw)

RADAR is an electromagnetic system for the detection and location of target objects such as aircraft, ships, spacecraft, vehicles, people, and the natural environment which can refl ect a signal back. It uses electromagnetic radio waves to determine the angle, range, or velocity of objects. RADAR was developed by various nations before and during Second World War. RADAR is a classic example of an electronic engineering system that utilizes many of the specialized elements of technology practiced by electrical engineers, including signal processing, data processing, waveform design, electromagnetic scattering, detection, parameter estimation, information extraction, antennas, propagation transmitters, and receivers. This paper gives an outline of RADAR principle and some of the RADAR applications, which range from air traffi c control, forest and climate monitoring and the monitoring of natural disasters, to name just a few.
