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 ...
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 fire control radar for CIWS gun on Soviet aircraft carrier Minsk, Russia. 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 ...
A millimeter wave scanner is a whole-body imaging device used for detecting objects concealed underneath a person’s clothing using a form of electromagnetic radiation. Typical uses for this technology include detection of items for commercial loss prevention , smuggling , and screening for weapons at government buildings and airport security ...
AN/APQ-57 millimetre wave navigational radar; AN/APQ-58 millimetre wave navigational radar; AN/APQ-59 improved AN/APQ-56 side looking radar by Westinghouse Electric (1886) AN/APQ-60 missile illumination radar by Raytheon for semi-active radar homing missiles; AN/APQ-62 side looking radar; AN/APQ-64 Sparrow II missile control radar for F5D Skylancer
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 .
The AGM-114L, or Longbow Hellfire, is a fire-and-forget weapon: equipped with millimeter-wave (MMW) active radar homing, it requires no further guidance after launch—even being able to lock on to its target after launch [18] —and can hit its target without the launcher or other friendly unit being in line of sight of the target. It also ...
