ABSTRACT:
A system for calibrating waveform generators and receivers of non-overlapping electronic scanning antennas includes a first sub-array, a second sub-array and a calibration cable. The first sub-array includes a first waveform generator, a first receiver, and a first switch assembly. The second sub-array includes a second waveform generator, a second receiver, and a second switch assembly. The calibration cable is configured to selectably form a common calibration path between the first and second sub-arrays based on a position of the first and second switch assemblies. The first and second switch assemblies are configured to enable calibration of the second receiver using an input from the first waveform generator via the calibration cable.
