Abstract

PURPOSE:To correct the deviation from a normal route by turning and scanning laser beams of sharp directivity around two fixed points, specifying the route of a moving object by the loci drawn by the points of intersection thereof, and detecting the two signals on the moving object. CONSTITUTION:Scanning signal generators 2a, 2b are provided spacially by a prescribed spacing, and signals of different frequencies having sharp directivity for example, laser beams 3a, 3b are turned and scanned in opposite directions at a constant speed. If the laser beams 3a, 3b scan by maintaining thetaa1=thetab1, thetaa2=thetab2,... from, for example, a direction PO, the straight line connecting the P0, P1 is the locus of the points of intersection of the beams 3a, 3b. This is used for guiding of, for example, aircraft and ships. When an angle thetaan=thetabn, the laser beams are modulated by the distance information from the P0 up to the Pn. A moving object receives both beams, and knows wether it is on the course or off to either side from whether both beams are received simultaneously or received with a time difference. It also knows distance information. Thereby, the course deviation of the moving object is corrected and safe operation is carried out.
