Abstract: The present invention concerns a method for eliminating interference in measuring signals (SM) which are corrupted by pulsed interference signals (SST) having a known or determinable interference pulse interval (TSt), whereby the detection period (?tE) of an individual measured value (E) is shorter than an interference pulse period (?tSt), and a plurality of individual measured values (E) is detected at freely selectable time intervals (TE) of the measuring signal (SM). A reliable elimination of interferences caused by radio-interference sources transmitting in a pulsed manner is achieved by detecting at least three consecutive individual measured values (E) at time intervals (TE) that differ from the interference pulse interval (TSt), and by determining an interference-filtered measured quantity (M) with the at least three individual measured values (E).

Abstract: An apparatus includes a plurality of sensor modules that are disposed at spacings with respect to one another, each sensor module having a local oscillator device. The oscillator device generates an oscillator signal that is passed on to a transmit/receive device, and the oscillator signal is radiated. The transmit/receive device is set up such that it can receive signals reflected from the object. A phase detection device is coupled at one input to the oscillator device and at a second input to the transmit/receive device. Based on the oscillator signal and the received reflected signals, the phase detection device determines a phase signal. A control and signal-processing device determines, based on the spacings of the sensor modules with respect to one another and the phase signals, a direction of the object with respect to the sensor module.
