Research of beamforming network based on micro-ring resonator in optically controlled phased array radar

Abstract

In order to realize multi-function, the radar has wide instantaneous bandwidth and working bandwidth. Unfortunately, the traditional phased array radar antenna by microwave phase shifter in the way of phasing. This paper presents a kind of wideband phased array antenna based on array element micro-ring resonator delay and subarray optical switch, and performance simulation to the proposed antenna system. The simulation results shows that the proposed antenna system can be more effectively satisfied with requirement of wideband and wide-angle scanning of phased array radar.
