Abstract
A system for calibrating conformal ESAs includes a rotating platform (positioner) or multiple test probes, or both. Measurements are taken with different radiating elements at different azimuthal angles to the test probes and compared to a known profile to compute correction coefficients for angel and gain for each radiating element. Each radiating element is operated at full power and across a wide frequency spectrum to acquire measurements including coupling and allow calibration to be based on group delay over the frequency spectrum rather than phase delay.
