Mitigation of polarization mismatch between reflector and feed antennas by feed predistortion

An apparatus comprising:

• a horn-type feed unit, including a first pin disposed through a first interior side of the feed unit, and a second pin disposed through a second interior side of the feed unit, the second interior side being orthogonal to the first interior side;
• a reflector unit;
• a controller configured to excite the first pin and the second pin to generate the first wave having the compensated polarization;
• and
• one or more sensors;
• and
• wherein the feed unit is configured to generate a first wave having a first polarization,
• wherein the reflector unit is configured to reflect at least a re-radiated wave,
• wherein the re-radiated wave reflects a second polarization associated with the reflector unit, the second polarization being mismatched relative to the first polarization,
• wherein the feed unit is configured to pre-distort the first wave to achieve a compensated polarization for reducing and/or eliminating the polarization mismatch, and to output the pre-distorted first wave having the compensated polarization,
• wherein the one or more sensors is/are configured to determine at least one property of one or more of the first wave, the pre-distorted first wave, the re-radiated wave, a scattered wave reflected by the reflector unit, and a specular wave reflected by the reflector unit;
• and
• wherein the controller is configured to adjust the pre-distorting of the first wave based on the determined at least one property, and
• wherein a level of the re-radiated wave is increased as a result of the pre-distortion.
