The present invention is a method and an apparatus for guiding a rotating moving body to keep it on course towards a target, this method and apparatus comprising emitting electromagnetic radiation, with the aid of a radiation emitter having a variable-focus optical system enabling the body to be followed during its flight, having a very short wave length and in the form of a beam which is amplitude modulated in such a way that different areas over a cross section of the beam in a plane passing through the body being guided contain respectively radiation of high and low intensity, sweeping this beam with at least one radiation detector mounted on the body being guided and calculating, from the signals emitted by one or more detectors, the data necessary for automatically guiding the body along an axis extending between the center of the amplitude modulated beam and the target.

Method and apparatus for guiding a rotating moving body

An amplifier for an electromagnetic radiation receiver has a plurality of amplification channels for the determination of angular separations, especially for use in self guiding equipment in missiles in which each amplification channel has several amplification stages each of which is of fixed gain. Means are provided to vary the number of operational stages as a function of the sum of the outputs of the channels. A converter is disclosed for converting the analog signal values to stochastic values. A division process is disclosed for the data, based on the use of simple operator and stochastic values.
