Paper Abstract

A wideband time-domain approach is described for the calibration of an L-band photonic array antenna using time shifters. A nanosecond pulse was injected into each channel with the time shifter cycling through all the states so that the insertion loss and the time delays could be calibrated. The pulse was not generated in real time; it was instead synthesized with 801 frequencies over a wideband (50%) from 850 to 1400 MHz. The network analyzer transmits the cw frequencies one at a time over a period of 100 ms, and the measured data are transformed into the time domain with the built-in FFT.
