Antenna system, method and computer program product, with real time axial ratio polarization correction

A method for controlling an antenna system operative in conjunction with an airborne transmitting segment and moving ground receiving segments having polarization therebetween, the polarization having an axial ratio, the method comprising:

• providing at least one processor in respective data communication with at least one receiving segment in motion on the ground including an antenna;
• and
• providing computer memory which is accessible to said processor and which stores a computer representation indicative of at least one desirable polarization behavior parameter of the airborne transmitting segment, for each of multiple relative locations of the airborne and ground segments,
• the processor being operative:
• to provide a current relative location of the airborne transmitting segment and receiving segment/s on the ground,
• to access an desirable polarization behavior parameter associated with the current relative location of the airborne segment and receiving segment/s on the ground from said computer representation,
• to access a current polarization behavior parameter of at least one of said receiving segment/s′ antenna,
• to compute a real time adjustment of the polarization's axial ratio which, if applied to the receiving segment antenna, will change the receiving segment antenna's polarization behavior parameter from said current polarization behavior parameter to said stored polarization behavior parameter, and
• to feed said real time adjustment to said at least one receiving segment antenna.

A computer program product, comprising:

• a non-transitory tangible computer readable medium having computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for controlling an antenna system operative in conjunction with an airborne transmitting segment and moving ground receiving segments having polarization therebetween, the polarization having an axial ratio, the method comprising:
