Photonic angle of arrival and time dif ference of arrival measurement based on d

We propose and experimentally demonstrate a photonic approach to estimate the time-difference-of-arrival (TDOA) and the angle-of-arrival (AOA) of a microwave signal. TDOA and AOA are estimated from the carrier power difference of the two outputs of the Mach-Zehnder modulator (MZM) using only one dua
