Patent ID: 7084807

Claim:
A method for generating HF signals for determining a distance and/or a speed of an object, having the following steps: generating a pulsed modulated signal ( 6 ′) from a first signal ( 3 ) and a second signal ( 4 ) in a signal generator ( 31 ; 1 , 2 , M 1 , 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 ; M 2 , 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 ; M 3 , 16 , 17 , 18 ).
