摘要：A laser radar apparatus for producing a pulse modulated transmitted lightbeam and receiving reflected light beams from road mounted retroreflectors. In thepreferred embodiment, a floodlight beam illuminates a portion of a roadway from 20 to150 in front of a vehicle. Reflected beams from retroreflectors mounted in the roadwayare received by the radar unit which calculates distance D and angle ϑ between the laserradar apparatus and each retroreflector. Distance D is calculated by measuring thepropagation delay of the pulse modulated light beam. Angle ϑ data is indicated bymeasuring where on a receiver photodiode array the light beam is incident.
