Abstract

Et radarapparatet overvåker fra en opphoyet plass et veiområde hvorved hastigheten og klassifiserings- kjcnnetegnene til kjorctoyet bestemmes i forskjellige avstandsområder med hensyn til radarapparatet. I den forbindelse blir hastigheten målt i et fjerntliggende og kjoretoyomrissct minst i et nærliggende avstandsom- råde. Med en ekstra modulasjon av radarsenderen til trafikkradarapparatet blir det gjennomført en av- standsseleksjon og hermed måles silucttcn av kjorc- toyet for klassifisering, l den forbindelse kan det såvel for hastighctsmålingen som også for klassifise- ringen benyttes flere radarstråler. For hastighetsmålingen kan det benyttes overlappende peilestrålcr. For å oppnå bedre konturskarphet blir med bruk av metoder for smalere peiling de for klas- sifisering målte radarsignaler korrelert med et på for- hånd beregnet tidsmessig signalforlop som er bestemt ved radarparametre, oppstillingsgeometri samt den på forhånd målte hastighet av det kjøretoy som skal klassifiseres.A radar apparatus monitors from a raised space a weighing area whereby the speed and classification characteristics of the vehicle are determined in different ranges of range with respect to the radar apparatus. In this connection, the speed is measured in a remote and vehicle toy area at least in a nearby distance area. With an extra modulation of the radar transmitter to the traffic radar apparatus, a distance selection is carried out and thus the silucton of the vehicle for classification is measured, for this connection can be used for the speed measurement as well as for the classification several radar beams. For the speed measurement, overlapping beams can be used. In order to achieve better contour sharpness, using methods for narrower bearing, the radar signals for classification are correlated with a predetermined temporal signal loss determined by radar parameters, alignment geometry and the predetermined speed of the vehicle to be classified.
