Abstract

Objektdeteksjonsanordning (40) innbefatter en sender- enhet (44) og en mottakerenhet (10). Mottakerenheten innbefatter et mottakerelement (12) som har en inngangsapertur (16) for mottagelse av elektromagnetisk stråling som reflekteres fra et objekt. Mottakerel- ementet innbefatter dessuten en utgangsapertur (24) og en buet overflate (22) som er anbragt relativt inngangsaperturen for reflekterlng av ialt vesentlig all elektromagnetisk stråling (A.B.C), som reflekteres fra et objekt på en avstand som overstiger et aktuelt område, til utgangsaperturen. En første strålings- detektor (14) er anbragt ved utgangsaperturen for mottagelse av objektstrållng som reflekteres til denne og for å frembringe et første elektrisk signal. En andre strålingsdetektor (30) er anbragt på et sted på mottakerenheten for mottakelse av objektstråling som reflekteres til denne reflektert fra et objekt på en avstand som er Innenfor det aktuelle området. Anordningen innbefatter dessuten kretser (32, 34, 35, 36, 37, 38, 39) for å kombinere det første elektriske signalet med det andre elektriske signalet for i alt vesentlig å eliminere en komponent i det første elektriske signalet som skyldes elektromagnetisk stråling som reflekteres fra et objekt innenfor det aktuelle området.
