  2. Marine radar - Wikipedia

    en.wikipedia.org/wiki/Marine_radar

    Any ships or obstructions reflect microwaves back to the antenna, displaying on the radar screen. Marine radars are X band or S band radars on ships, used to detect other ships and land hazards, to provide bearing and distance for collision avoidance and navigation at sea. [1] They are electronic navigation instruments that use a rotating ...

    en.wikipedia.org/wiki/Seaspray_(radar)

    Seaspray is a monopulse radar that produces 90 kW in the I band (formerly known as the X-band). The semi-parabolic reflector was made of lightweight foam with a wire mesh to make the system as light as possible. The system scanned 180° in azimuth by rotating the reflector and feed horn together and scanned vertically by moving the reflector ...

    The Coastal Surveillance Radar (CSR) was developed by the Electronics and Radar Development Establishment (LRDE) in Bangalore, Karnataka, and is the primary sensor of the ICSS. The radars operate round the clock in all weather conditions and are capable of detecting smaller vessels such as trawlers, dinghies, dhows, fishing vessels and buoys.

    en.wikipedia.org/wiki/History_of_radar

    The Digital Airport Surveillance Radar (DASR) is a newer TRACON radar system, replacing the old analog systems with digital technology. The civilian nomenclature for these radars is the ASR-9 and the ASR-11, and AN/GPN-30 is used by the military. In the ASR-11, two radar systems are included.

  8. Automatic radar plotting aid - Wikipedia

    en.wikipedia.org/wiki/Automatic_radar_plotting_aid

    A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] The system can calculate the tracked object's course, speed and closest point of approach [2] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass. Development of ARPA started after 1956, when the ...

  9. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [ 1 ] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
