<p>Directional relays which are locked onto the same frequency and whose antennas consist of directional groupings of elementary antennas spatially offset by lambda /4 are arranged along a road. The output signal from one or more transmitters from the chain is phase-shifted (4) by half a wave (180 DEG ) so as to compensate the deformations in the curve of the signal transmitted by each relay and which are due to the differences in time of travel of the various signals received and added in this and/or the preceding relays. <IMAGE></p> |
