摘要： A system for determining the deviation of an object from a reference line, in particular for determining the deviation of a guided missile from a sight line extending from the missile launcher to a target, comprises a transmitter assembly at the origin of the reference line and a receiver assembly in the object. The transmitter assembly includes a radiation beam projecting device emitting a radiation beam in the direction of the reference line, this radiation beam being such that in planes perpendicular to the reference line it produces a radiation pattern composed of two elongated narrow radiation strips, which are mutually perpendicular and sweep alternatingly and periodically with a predetermined sweeping frequency over the reference line in directions at right angles to their respective longitudinal directions. The receiver assembly in the object includes a radiation detector mounted to be activated by the radiation beam so as to generate an electric output signal which is modulated in response to the movement of the radiation pattern of the radiation beam relative to the radiation detector, and signal processing circuits receiving the output signal from the radiation detector and including time measuring means for determining the time interval between each passage of a radiation strip over the radiation detector and a reference time corresponding to a predetermined position of the radiation strips relative to the reference line.
