The invention relates to calibrating a device or a system for signal-transit-time measurement or signal-transit-time-measurement-based distance measurement on the basis of at least one phase measurement. A method for calibrating at least one system for carrying out a signal-transit-time measurement where the system is designed, in cooperation with a first object, to carry out a distance measurement on the basis of a phase measurement, at least one first distance measurement to the first object being carried out by means of phase measurement, particularly by phase shifting and/or modifying a phase shift by the frequency, and at least one signal-transit-time measurement or a second distance measurement carried out on the basis of at least one signal-transit-time measurement to or via the first object. The system is calibrated on the basis of at least one signal-transit-time measurement by means of the at least one first phase measurement.
A method for calibrating at least one system for carrying out one or both of a signal time-of-flight measurement and a signal time-of-flight difference measurement, wherein the system is configured in cooperation with a first object, to carry out a distance measurement on the basis of a phase measurement, wherein at least one first distance measurement to the first object is carried out by means of the phase measurement, and at least one signal time-of-flight measurement or a second distance measurement is carried out on the basis of at least one signal time-of-flight measurement to or via the first object, wherein the system for carrying out further signal time-of-flight measurements or distance measurements or position-finding is calibrated by means of the at least one first phase measurement on the basis of at least one signal time-of-flight measurement, or signal time-of-flight difference measurement.
A use of at least one phase measurement on at least one signal between a first object and at least one second object for calibrating at least one apparatus or system for signal time-of-flight measurement or signal time-of-flight difference measurements or signal time-of-flight-based- or signal time-of-flight-difference-based distance measurement or position-finding of the first object or of at least one second object.
