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 ...
Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
Millimeter-wave cloud radars, also denominated cloud radars, are radar systems designed to monitor clouds with operating frequencies between 24 and 110 GHz (Table 1). Accordingly, their wavelengths range from 1 mm to 1.11 cm, about ten times shorter than those used in conventional S band radars such as NEXRAD .
Millimeter wave radar is used in short-range fire-control radar in tanks and aircraft, and automated guns on naval ships to shoot down incoming missiles. The small wavelength of millimeter waves allows them to track the stream of outgoing bullets as well as the target, allowing the computer fire control system to change the aim to bring them ...
It is possible for a system other than the launching platform to provide guidance to the missile before it switches its radar on; This may be other, similar fighter aircraft or perhaps an AWACS. Most anti-ship missiles use active radar homing for terminal guidance. Many ARH missiles with targets on land or sea use millimeter wave guidance.
Enhanced vision is a related to Synthetic vision system which incorporates information from aircraft based sensors (e.g., near-infrared cameras, millimeter wave radar) to provide vision in limited visibility environments. Night vision systems have been available to pilots of military aircraft for many years.
