Abstract:
PCT No. PCT/DE96/01673 Sec. 371 Date Mar. 9, 1998 Sec. 102(e) Date Mar. 9, 1998 PCT Filed Sep. 6, 1996 PCT Pub. No. WO97/09637 PCT Pub. Date Mar. 13, 1997For improving the measuring precision, a reference unit (REF) is juxtaposed with a continuous wave radar (DSR). This reference unit (REF) comprises a surface wave element (OFW) for generating a signal delayed relative to the transmission signal. A mixed signal is formed from the delayed signal and the transmission signal with a mixer (MI2), this mixed signal being utilized in combination with the measured signal stemming from the continuous wave radar (DSR) for determining the distance.
