REFLECTOR DISTORTION COMPENSATION DEVICE FOR MULTI-BEAM WAVES RECEIVING AND / OR TRANSMITTING ANTENNAS

摘要

The invention relates to devices of the type comprising means for detecting the reflector's distortions, means for generating an error signal controlled by said detecting means and means 4 for correcting the distortions. OF THE REFLECTOR COMMANDED BY THIS ERROR SIGNAL. / P P THE PROBLEM TO BE SOLVED IS TO ALLOW DIRECT PRODUCTION OF THE ERROR SIGNAL, AND WHATEVER THE METHOD OF CORRECTION USED. / P P According to the invention, the means of detection comprise a transmitter of RF signals located at a distance and cooperating with the grouping of primary sources 1 of the beam forming network which is in the receiver mode and comprises a central source and peripheral sources. SYMMETRICAL ARRANGEMENT AND ERROR SIGNAL PRODUCTION MEANS INCLUDE AN ADDITION CIRCUIT CONNECTED TO TWO OF THE PERIPHERAL SOURCES. / P P THE INVENTION FINDS AN ADVANTAGEOUS APPLICATION ON SATELLITE MOUNTED ANTENNAS. / P
