Abstract

A novel phase modulation parallel optical delay detector is proposed for microwave angle-of-arrival measurement with accuracy monitored by using only one dual-electrode Mach–Zehnder modulator. A theoretical model is built up to analyze the proposed system including measurement accuracy monitoring. The spatial delay measurement is translated into the phase shift between two replicas of a microwave signal. Thanks to the accuracy monitoring, the phase shifts from 5° to 165° are measured with less than 3.1° measurement error.
