Abstract
A device for determining a speed of an object, having a receiver for receiving a pulse, having a characteristic signal sequence, which is emitted or reflected from an object; a signal processing device for providing transformed signal sequences for various speeds, the signal sequences being determined from the characteristic signal sequence by transforming the time axis of the signal sequence according to a Doppler shift for the speed; and a data processing device for determining the speed of the object based on a correlation of the received pulse with the transformed signal sequences.
Claims8
A method for determining a speed of an object, comprising:
- receiving, by a receiver, a pulse having a characteristic signal sequence, which is emitted or reflected from an object;
- providing, by a signal processing device, transformed signal sequences for various speeds, the signal sequences being determined from the characteristic signal sequence by transforming a time axis of the signal sequence according to a Doppler shift for the speed;
- determining, by a data processing device, a correlation of the received pulse with the transformed signal sequences;
- and
- determining, by the data processing device, the speed of the object based on the determined correlation.
