Navy, had a transmitter and a receiver on opposite sides of the Potomac River and discovered that a ship passing through the beam path caused the received signal to fade in and out.

He also got a British patent on Septem for a full system, that he called a telemobiloscope.Ī Chain Home tower in Great Baddow, United Kingdom He obtained a patent for his detection device in April 1904 and later a patent for a related amendment for estimating the distance to the ship. In 1904 he demonstrated the feasibility of detecting a ship in dense fog, but not its distance from the transmitter. The German inventor Christian Hülsmeyer was the first to use radio waves to detect 'the presence of distant metallic objects'. In his report, Popov wrote that this phenomenon might be used for detecting objects, but he did nothing more with this observation. In 1897, while testing this equipment for communicating between two ships in the Baltic Sea, he took note of an interference beat caused by the passage of a third vessel. The next year, he added a spark-gap transmitter. In 1895, Alexander Popov, a physics instructor at the Imperial Russian Navy school in Kronstadt, developed an apparatus using a coherer tube for detecting distant lightning strikes.

One example is ' lidar', which uses visible light from lasers rather than radio waves.Īs early as 1886, German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects. Other systems similar to radar make use of other parts of the electromagnetic spectrum. High tech radar systems are associated with digital signal processing and are capable of extracting useful information from very high noise levels.

The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems marine radars to locate landmarks and other ships aircraft anticollision systems ocean surveillance systems, outer space surveillance and rendezvous systems meteorological precipitation monitoring altimetry and flight control systems guided missile target locating systems and ground-penetrating radar for geological observations. The term radar has since entered English and other languages as the common noun radar, losing all capitalization. The term RADAR itself, not the actual development, was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging. Radar was secretly developed by several nations before and during World War II. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter. The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. Radar is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It rotates steadily sweeping the airspace with a narrow beam. Radar of the type used for detection of aircraft.
