Abstract: A method for detecting the position of a piston of a piston cylinder is provided. A microwave transmit signal is emitted in the direction of the piston and microwaves reflected from the piston are detected. The transmit signal is a modulated signal with a base frequency sinusoidally modulated at a modulation frequency. An evaluation of the phase between transmit signals and receive signals is performed. A phase determination at the baseband and a simultaneous phase determination at at least one sideband are also performed. The phase determination at the baseband is used for fine determination of the piston position and the phase determination at the at least one sideband is used for coarse determination of the piston position. Bandpass filtering on receive signals and evaluation transmit signals is performed with respect to the base frequency or an intermediate frequency. Bandpass filtering is performed with respect to the modulation frequency.

Abstract: A method for operation of a distance sensor emits a transmission signal as transmission radiation, reflected by an object, the distance of which is to be measured, as reflection radiation, and received as a reflection signal. The reflection signal and a reference signal that occur at a receiver input are regulated to a predetermined ratio. The distance is determined during the regulation process. An auxiliary transmission antenna emits an auxiliary transmission signal as auxiliary measurement radiation, directly toward a reception antenna. Microwaves are used as the transmission and auxiliary transmission signals. The reception antenna receives the reflection radiation reflected by the object and passes it on to the receiver input as a reflection signal. The reception antenna receives the auxiliary measurement radiation directly and passes it on to the receiver input as an auxiliary reception signal which is evaluated as a reference signal when measurement radiation emission is suppressed.
