Abstract
For an angle-resolving antenna system, only two radar sensors are provided including separate transmitting and receiving antennas. The receiving antennas of the two radar sensors are switchable with reference to their main beam direction as well as to their beam width.
Claims5
An angle-resolving antenna system for pulse radar applications in automotive technology, comprising:
- two radar sensors for determination of distance information and angular deviation, each of the two radar sensors including a separate transmitting antenna and receiving antenna;
- an evaluation unit for obtaining the angular deviation from receiving signals of the two radar sensors in unlike switching states;
- and
- at least one column of antenna exciters that is capable of being switched on and off for switching the beam width;
- wherein receiving antennas of the two radar sensors are configured to be switchable with regard to main beam direction and beam width.
