Abstract :
A new system suitable for phased array radar and imaging is proposed and demonstrated. This system is based on the time dependent nature of modern RF sensors and uses a novel optical serial feed which has all the advantages of true time delay and yet only requires one tunable laser, one optical modulator and one fiber optic grating delay
