Abstract
System and method for in-operation calibration of phased array antenna system, involv-ing outputting first and second calibration signals on separate calibration nets through same switches of transmit and receive modules (TRM) and transmit and receive feed network branches for detecting whether system is operational. Allows moreover, identifi-cation of drift in specific calibration net and compensation therefore.
