摘要：The present invention relates to a method and a corresponding device fordeter¬ mining the speed of a moving entity carrying at least two antennas for receiving atransmission signal, said antennas being displaced at a predetermined distance. In orderto provide a more simple and accurate method which can be used with differenttransmission signals a method is proposed comprising the steps of: receiving a
transmission signal by the at least two antennas, determining signal characteristics fromthe transmission signal as received by the at least two antennas, - determining a timeoffset between the reception of the transmission signal at the at least two antennas bycomparing the signal characteristics determined for the at least two antennas, anddetermining the speed of the moving entity from the determined time offset, thedistance of the at least two antennas and the direction of movement of the moving entityrelative to the arrangement of the at least two antennas.
