COLLIMATOR DEVICE FOR ELECTRIC ALIGNMENT OF ON-BOARD RADIO-LOCATING STATION ANTENNAS OF BIG SIZE IN LOW-SIZED ROOMS

摘要

FIELD: aviation; radiolocation.;SUBSTANCE: invention is related to radiolocation and may be used for electric alignment of on-board antennas, for instance airplane on-board antennas; on-board radio-locating stations (BRLS) in low-sized rooms. Device comprises rating range, BRLS, BRLS antenna located in forward part of airplane, laser sight, which is rigidly connected to BRLS antenna, axis of which is parallel to antenna axis and airplane axis, rating target with crossing, parabolic collimator with radiator installed in near Fresnel zone of BRLS antenna, target imitator, outlet of which is connected to inlet of collimator radiator, at that collimator is electrically connected to BRLS antenna. Device is additionally equipped with mechanism for displacement of collimator radiator, alignment target is arranged as radio transparent and optically semi-transparent and is located so that its plane is perpendicular to axis of collimator paraboloid, and central crossing coincides with its focus, part of collimator web inverted to laser sight is arranged as mirror-reflecting. Airplane is oriented relative to collimator so that highlight on alignment target from laser beam reflected from mirror surface of collimator is located inside circle of certain radius.;EFFECT: simplification and cost reduction of manufacturing.;1 dwg
