SYSTEM AND METHOD OF FORMING a beam of waves from mobile antenna with respect to each other.

The present invention relates to an electronic method for forming a beam of electromagnetic waves to point to an object (108) from multiple transmitting antennas omnidirectional (112, 114, 116), each antenna being mounted on a platform ( 102, 104, 106), the platforms bearing the antennas being spaced from and movable relative to each other, said method comprising at least the following steps, repeated over time: ▪ at least two platforms (102, 104 ) determines its absolute position by locating means (402); ▪ determine the distance between the platforms (102, 104, 106) by means (408, 410) more accurate than the location means (402); ▪ determine the precise positions of the platforms from the absolute positions and distances previously determined; ▪ the antenna of each platform (102, 104, 106) emits an electromagnetic wave whose phase is selected according to the position of the platform, so that the waves from each antenna arrive in phase on 'pointed object (108). The invention applies in particular to interference from terrestrial radio devices.
