Method for operating a distance sensor and device for performing the method

The invention relates to a method for operating a distance sensor (10). In the method, a transmission signal (S1) is radiated as transmission radiation (S2), reflected as reflection radiation (S3) by an object (16), the distance (D) of which is to be measured, and received as a reflection signal (S4...

Zusammenfassung:	The invention relates to a method for operating a distance sensor (10). In the method, a transmission signal (S1) is radiated as transmission radiation (S2), reflected as reflection radiation (S3) by an object (16), the distance (D) of which is to be measured, and received as a reflection signal (S4). The reflection signal (S4) present at a receiver input (28) and a reference signal likewise occurring at the receiver input (28) are controlled to a specified ratio, the distance (D) being determined during the adjusting process. The invention further relates to devices for performing the method. The method is characterized in that microwaves are used as the transmission radiation (S2) and a cross-talk signal (S5, S6) from the transmission signal (S1) directly to the receiver input (28) with suppressed radiation of the transmission signal (S1) is used as the reference signal.
