Abstract
A system for insitu AESA calibration includes a radar receiver/excitor (XR). The calibrated XR functions as a precision multi-channel relative amplitude and phase microwave frequency measurement device that executes a known AESA calibration methodology. An integrated RF sensor system-level built in test (BIT) is utilized for prognostic health monitoring and self-healing calibration. During calibration, quadrants of the AESA are iteratively calibrated via measurements by the XR. I/Q values are balanced for each quadrant relative to each other without the need for a separately calibrated measurement device for absolute calibration. A near field probe may be disposed for radiative loopback measurements. A T/R calibration circuit receives the loopback measurements and data from a Tx channel.
