Millimeter Wave Radar Sensor Wikipedia

In 2009 darpa provided funding to develop sandblaster a millimeter wave radar based enhanced vision system installed on helicopters which enables the pilot to see and avoid obstacles in the landing area that may be obscured by smoke.

Millimeter wave radar sensor wikipedia. 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 at government buildings and airport security checkpoints.

Other sensor types have been flown for research purposes including active and passive millimeter wave radar. A radar sensor used in 2003 model mercedes s class automobiles.

Radar is a detection system that uses radio waves to determine the range angle or velocity of objects. 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 together. The market for driver assistance systems based on millimeter wave radar sensor technology is gaining momentum. It can be used to detect aircraft ships spacecraft guided missiles motor vehicles weather formations and terrain a radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain a transmitting antenna a receiving antenna often the same.

Several countries employ the scanners for security. In the near future the full range of newly introduced car models will be equipped with radar based systems which leads to high volume production with low cost potential.
