ABSTRACT:
The present invention provides a method for generating HF signals for determining a distance and/or a speed of an object, having the following steps: generating a pulsed demodulated signal (6′) from a first signal (3) and a second signal (4) in a signal generator (31; 1, 2, M1, 7, 8); with a transmitting device (20), sending the pulsed modulated signal (6′) in the direction of an object (40); with a receiving device (21), receiving a pulsed signal (6″) reflected by the object (40); generating a pulsed demodulated signal (4″) from the received signal (6″) and the first signal (3) in a first signal processor (32; M2, 15); and generating a coherent signal (23) from the pulsed demodulated signal (4″) and the second signal (4) and a noncoherent signal (22) from the pulsed demodulated signal (4″) in a second signal processor (33; M3, 16, 17, 18). The present invention also provides an apparatus for generating HF signals for determining a distance and/or a speed of an object.
