The Corner Radar is designed for various applications. Motion signals detected by the radar chip are transformed into multiple representations, including range doppler, which helps map the location of a hand by its velocity and distance from the sensor. radar sensors are not controllable or able to coordinate with sensors on other vehicles. The first operational systems are on the market since 1992 for buses and trucks and 1999 for passenger cars, both in the frequency range around 24 as well as 76. No more need to install two radar systems, one for Long Range and another for Middle Range, the 77GHz Multi Mode Radar combines both. New receiver & transmitter.
