Beschreibung
Zusammenfassung:	A radar sensor device. The radar device includes a radar sensor for detecting an object using radar waves, a transmission path which transmits a transmission signal in the direction of the object and includes a transmission antenna, at least one receiving path which transmits a transmission signal reflected by the object as a reception signal and includes a receiving antenna and a test signal path which transmits a test signal for self-testing the radar sensor and extends at least between a first coupling point of the transmission path and a second coupling point of the receiving path. The first coupling point is disposed in the direction toward the object downstream of the transmission antenna or immediately upstream of the transmission antenna and the second coupling point is disposed in the direction coming from the object upstream of the receiving antenna or immediately downstream of the receiving antenna.
