Arrangement for generating and automatic tracking of antenna diagrams in elevation for aircrafts during flight manoeuvres with the purpose of data transmission
The arrangement has an antenna array of several antennas (39,49) with associated feeder (11-15) networks with transmitter and receiver branches (21,22). The antenna diagram is tracked using a control signal derived from the attitude angle of the aircraft in elevation so that the radiation or recepti...

| Zusammenfassung: | The arrangement has an antenna array of several antennas (39,49) with associated feeder (11-15) networks with transmitter and receiver branches (21,22). The antenna diagram is tracked using a control signal derived from the attitude angle of the aircraft in elevation so that the radiation or reception direction is always horizontal. Transmitted and received signals are phase shifted to produce the antenna diagram using delay lines (33a,33e,..) and mixers (31). |
