Complex gain computation of direction finding C band array antennas mounted in motor gliders pods

The location of electromagnetic sources on the ground could be considered by installing array antennas on the fuselage of aircraft or drones flying on specific trajectories. The analysis of phase delays between the emitting ground source and the receiving antennas mounted on the aircraft allows to determine accurately the electromagnetic source direction. However we must take into account the flight conditions during the analysis as the vibrations of the array and the coupling of the array receiving antennas due to multipath interactions with the structure of the aircraft. We are interested in the computation of the differential phases of 8 wide band spiral antennas installed in a pod mounted under the wing of a STEMME motor glider.
