Dual-band Microwave Photonic Radar based on a Photonic-Assisted Stretch Processing Receiver

Abstract

A dual-band linear frequency-modulated continuous-wave (LFMCW) microwave photonic radar is proposed and demonstrated. The system is capable of operating at different bands independently and simultaneously based on a photonic-assisted stretch processing receiver. An experimental demonstration is conducted, operating at C-band and Ku-band with a bandwidth of 700MHz and 3600MHz respectively. A series of tests in a microwave anechoic chamber are performed. The results verify the concept of the dual-band microwave photonic radar, which provides a photonic solution to multi-band radar based on a unified system.
