Abstract (en)

[origin: EP0047479A2] 1. A method of transmission of guide data to an air-borne receiver attached to a controllable missile, by means of modulated electromagnetic radiation from a radio-control transmitter, characterised in that the radiation lobe width of the radio-control transmitter is varied in dependence upon the instantaneous distance between the missile and the radio-control transmitter, an indication of which is present at the radio-control transmitter, such that the receiver in the missile continually receives the level of received power required for an efficient signal-to-noise ratio.
