Described herein is an apparatus and a method for an antenna array calibration device and method. The device comprises a radio frequency/optical (RF/optical) data center having at least one optical input/output; N single mode fibers (SMF) each having a proximal end connected to the at least one optical input/output of the RF/optical data center and a distal end, where N is a positive integer; N optical/RF dish calibrators each having an optical input/output connected to the distal end of the at least one SMF input/output; N coaxial transmission lines each having a proximal end connected to one of the RF input/output of the N optical/RF dish calibrators and a distal end; and N dish antennas each connected to the distal end of one of the N coaxial transmission lines.

Antenna array calibration device and method

Methods and apparatus to calibrate an array by sequentially calibrating elements in a subarray with respect to each other using a satellite. The satellite is repeatedly illuminated for calibrating the elements using reference elements to determine plane fronts from which active elements can be calibrated with respect to each other.
