Microwave Photonic Distributed Radar System

6-8 GHz mw / 1549.7 nm photonic demonstration,

Joint optical polarization multiplexing and sideband multiplexing techniques demonstrate a basic capability to deploy four remote radar transceivers at a single optical wavelength and offer the potential for much larger scale distributed systems by WDM and TDM approaches to the optical network design.

Distributed radar systems for low-slow-small target detection with improved spectrum utilization, reduced probability of interference, improved 3D spatial coverage, enhanced target detection, and more effective mitigation and correlation of radar cross-section scintillation.

±3 cm 3D spatial positioning accuracy.
