Abstract

Fremgangsmåte for å måle distansen mellom et første objekt, som Innbefatter en sender-mottakerenhet, og et andre objekt, som Innbefatter en transponder. I henhold til oppfinnelsen sendes der fra sender-mottakerenheten (19) et første mikrobølgeslgnal (Sl), som mottas 1 transponderen (18). Et andre signal (S3) av slik lavere frekvens Fm genereres 1 transponderen og moduleres på et signal (S6) av mlkrobølgefrekvens 1 transponderen til å sende et modulert signal (S7). Det modulerte signalet (S7) sendes fra transponderen til sender-mottakerenheten (19), hvor det mottas bg blandes ned med det første signalet (Sl) og deretter a) lavpassfUtreres til å danne et første målesignal (S10) som har frekvensen Fm, hvis fase tilsvarer fase-dlfferansen mellom det første mlkrobølgeslgnalet (Sl) og mlkrobølgeslgnalet (S8) som mottas 1 sender-mottakerenheten (19) og b) demoduleres, for derved å danne et andre målesignal (S12) som har frekvensen Fm, hvis fase tilsvarer fasen for det andre signalet (S3) generert 1 transponderen (18). Fasene for de to måleslgnalene (S10, S12) sammenlignes 1 fasesammen-1 lgnlngskretsen (27) til å danne en differanse deri-mellom, Idet denne differanse er proporsjonal med. distansen mellom objekt
