Radar is a detection system that uses radio waves to determine the range angle or velocity of objects.
Millimeter wave radar sensor wikipedia.
A radar sensor used in 2003 model mercedes s class automobiles.
Other sensor types have been flown for research purposes including active and passive millimeter wave radar.
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.
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.
The circuits that transmit and receive millimeter waves are housed beneath the dome shaped plastic radome which is about 10 cm 4 inches in diameter.
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.
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.
The market for driver assistance systems based on millimeter wave radar sensor technology is gaining momentum.
