About Radar

Radar is a system for detecting objects that uses radio waves to determine the range, angle or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather and terrain formations. A radar system comprises a transmitter that produces electromagnetic waves in the radio or microwave zone, a transmission antenna, a receiving antenna (often the same antenna is used for transmission and reception) and a receiver and a processor for determining The properties of objects. The radio waves (pulsed or continuous) of the transmitter reflect the object and return to the receiver, providing information on the location and speed of the object.
Modern uses of radar are diverse, including air and ground traffic control, radar astronomy, air defense systems, missile systems, marine radars to locate landmarks and other ships, collision avoidance systems Aircraft, ocean surveillance systems, space surveillance and naming systems, rain-based climate monitoring, altimetry and flight control, guided missile tracking systems, ground penetration radars for geological observations and radar controlled range for Public health surveillance. High-tech radar systems are associated with digital signal processing, machine learning and are capable of extracting useful information from very high noise levels.
