Beschreibung
Zusammenfassung:	The invention concerns a Doppler radar kinemometer intended to measure the speed of a railway vehicle. According to the invention, it includes two antennas (1,2) mechanically connected to one another such that their axes form a determined angle between them. This angle is preferably between 60 DEG and 120 DEG . For safety operation, the antennas are each supplied with ultrahigh frequency waves (F1,F2) by their own wave generators (4,5), and each furnishes corresponding Doppler frequencies (Fd1,Fd2) to a distinct processing unit (11,12), with the signals coming from these two processing units then processed within a computing assembly (15) which supplies the value of the measured velocity.
