    en.wikipedia.org/wiki/AN/APG-78_Longbow

    The AN/APG-78 Longbow is a millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), which are housed in a dome located above the main rotor. [4] [5] The radome's raised position enables target detection while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The APG-78 ...

    These sets were installed on convoy escorts, enabling them to get fixes on U-boats transmitting from over the horizon, beyond the range of radar. This allowed hunter-killer ships and aircraft to be dispatched at high speed in the direction of the U-boat, which could be located by radar if still on the surface or ASDIC if submerged.

  6. Radar warning receiver - Wikipedia

    en.wikipedia.org/wiki/Radar_warning_receiver

    Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat.

  7. Radar engineering - Wikipedia

    en.wikipedia.org/wiki/Radar_engineering

    Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.

    The Air Route Surveillance Radar is a long-range radar system. It is used by the United States Air Force and the Federal Aviation Administration to control airspace within and around the borders of the United States. The ARSR-4 is the FAA's most recent (late 1980s, early 1990s) addition to the "Long Range" series of radars.
