Abstract

A photonic approach to the simultaneous measurement of the frequency, pulse amplitude (PA), pulse width (PW), and time of arrival (TOA) of an unknown pulsed microwave signal is proposed and demonstrated. The measurement is performed based on optical carrier-suppressed modulation, complementary optical filtering, low-speed photodetection, and electrical signal processing. A proof-of-concept experiment is carried out. A frequency measurement range of 2–11 GHz with a measurement error for frequency, PA, PW, and TOA within ±0.1GHz, ±0.05V, ±1ns, and ±0.16ns is achieved.
