This invention relates to a method, device, System and use to improve distance measurement between moving objects. It is known for distance measurements on the basis of phase angles, to realize movement corrections on the basis of several emissions which are performed simultaneously and on different frequencies from one object. This, however, requires synchronous emissions and simultaneous reception at the objects on different frequencies, which leads to an increase of the requirements of the respective objects or hard- and/or software respectively. It therefore is an object of the present invention, to provide a correction of movement influences in distance measurement on the basis of phase angles which can do without simultaneously emitting several waves or several frequencies respectively. This object is solved by a method for the correction of an influence to a distance measurement between at least two objects wherein from each of said at least two objects, particularly from all objects, at any given time only one signal is emitted, wherein the distance change and/or the change of the phase shift due to the distance change between said objects is determined between the individual transmissions and is taken into consideration in the determination of the distance. |
