Microwave proximity sensor and method for calculating the distance between a measuring head of a microwave proximity sensor and a target object

摘要

The microwave proximity sensor (10), to measure the distance between a target and the measurement head (18), has an evaluation unit (34) for an inferometric measurement of the microwaves from the transmitter(14) and at the receiver (16). A phase shift unit generates a signal and a second signal in a phase shift.
