Patent ID: 7095362

Claim:
A radar measuring device, in particular for a motor vehicle, with a high-frequency oscillating device ( 11 ) which emits a first carrier frequency signal (F 1 ) and a second carrier frequency signal (F 2 ), a first pulse-shaping device ( 12 ) which emits first pulse signals (P 1 ), a first switching device ( 14 ) which switches the first and second carrier frequency signals (F 1 , F 2 ) as a function of the first pulse signal (P 1 ) and emits first and second radar pulse signals (T 1 , 2 ), a transmission antenna ( 16 ) which sends out radar pulse signals (T 1 , 2 ), a second pulse-shaping device ( 23 ) which emits second pulse signals (P 2 ) which are delayed relative to the first pulse signals (P 1 ), a second switching device ( 24 ) which switches the first and second carrier frequency signals (F 1 , F 2 ) as a function of the second pulse signal (P 2 ) and sends out first and second delayed radar pulse signals (S 1 , 2 ), a receiving antenna ( 18 ) which receives first and second radar signals (R 1 , R 2 ), a mixing device ( 21 ) which mixes the received first and second radar signals (R 1 , 2 ) with the first and second delayed radar pulse signals (S 1 , 2 ) and emits first and second mixed signals (M 1 , 2 ), a control device ( 7 ) which determines an amplitude signal from the first mixed signal (M 1 ) and the second mixed signal (M 2 ), whereby a first phase difference between the first received radar signals (R 1 ) and the first delayed radar pulse signals (S 1 ) differs from a second phase difference between the second received radar signals (R 2 ) and the second delayed radar pulse signals (S 2 ).
