Project description
- In the area of driver assistance systems, a distinction is made between: passive systems such as cameras and active systems that evaluate the back reflection of a radiant energy (radar - or infrared - wavelength range) emitted by the respective sensor in a two-way measurement.
- Secondary radar is based on radar sensors used in medium- and long-range systems for object detection.
- For radar-based sensors in the field of driver assistance systems, the principle of "secondary radar" can be implemented in an advantageous way that helps to provide additional protection for objects with particular risk potential.
- Objects with increased risk potential carry a transponder that is activated by the radar sensor in the vehicle and, in addition to the reflected wave, communicates an additional message with the class of the object to the surrounding traffic.
