Abstract
PURPOSE:To enable to transfer a plurality of informations simultaneously by a method wherein the information to be transferred to the ground side from an unmanned vehicle is displayed by frequency. CONSTITUTION:A low wave cycle oscillator 11 is provided on each channel of a signal generating circuit 8, and an oscillation element, with which frequencies f11-f4n assigned to the channel of each oscillator 11 will be determined, or an oscillation constant circuit 11a is provided on each oscillator 11. The oscillation output of each oscillator 11 is transmitted from the transmitting coil 3, mounted on the lower surface of the unmanned vehicle, after it has been mixed by a mixer 7. The frequency of the signal received by the receiving coil 9 provided on the ground side is discriminated by the frequency discriminating circuit 18 located on a signal processing circuit 17. Accordingly, a pluratlity of informations can be transferred to the ground side simultaneously.
