  2. Terrain-following radar - Wikipedia

    en.wikipedia.org/wiki/Terrain-following_radar

    TSR-2 XR220 at RAF Museum Cosford, 2002. Ferranti developed the first terrain-following radar specifically for the TSR-2. Terrain-following radar (TFR) is a military aerospace technology that allows a very-low-flying aircraft to automatically maintain a relatively constant altitude above ground level and therefore make detection by enemy radar more difficult.

    A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...

  6. Height finder - Wikipedia

    en.wikipedia.org/wiki/Height_finder

    A height finder is a ground-based aircraft altitude measuring device. Early height finders were optical range finder devices combined with simple mechanical computers, while later systems migrated to radar devices. The unique vertical oscillating motion of height finder radars led to them also being known as nodding radar. Devices combining ...

  7. AN/SPY-6 - Wikipedia

    en.wikipedia.org/wiki/AN/SPY-6

    The SPY-6 system consists of two primary radars and a radar suite controller (RSC) to coordinate the sensors. An S-band radar is to provide volume search, tracking, ballistic missile defense discrimination, and missile communications, while the X-band radar is to provide horizon search, precision tracking, missile communication, and terminal illumination of targets.

  8. AN/MPQ-64 Sentinel - Wikipedia

    en.wikipedia.org/wiki/AN/MPQ-64_Sentinel

    The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [1] The system automatically acquires, tracks, classifies, identifies and reports high- and low-altitude targets, including cruise missiles, unmanned aerial vehicles, and both rotary- and fixed-wing aircraft.

  9. Nap-of-the-earth - Wikipedia

    Doppler radar has the potential to detect NOE flight, but the incoming aircraft has to be within radar range in the first place, and low flight minimizes this possibility by using hills and mountains to break the line of sight (terrain masking), defeating terrestrial air defense radar and in rough enough terrain also airborne early warning.
