Revolutionizing Doppler Radar With RF-Photonics
Abstract
We will discuss how to fundamentally improve radar systems by using RF-photonics in two ways: 1). Using a fiber-optic recirculation loop based interferoceiver to realize true correlation. It is an optimum extra-wideband radar receiver capable of measuring Doppler beating with a single pulse. Thsi eliminates Doppler range ambiguity. In addition, micro-Doppler signatures of any target become clearly recognizable for passive identification to prevent fratricide. 2). Further reduce the phase noise in an ultra-low-phase-noise opto-electronic oscillator (OEO) by eliminating RF amplifiers in the OEO loop to meet the requirement for low-speed Doppler detection and week signal detection.
