Wide-area marine ecological sensing system based on distributed microwave photonic radar architecture, achieving real-time continuous monitoring of sea surface temperature, salinity, wave, flow field and maritime targets.
OceanSente is a distributed photonic sensing system for marine environment monitoring. It leverages K25 distributed microwave photonic radar all-optical signal distribution and collaborative detection technology, and K7 microwave photonic phased array architecture for multi-node optically controlled beamforming, forming a wide-area sensing network covering over 50km radius. The system core uses K3 optical true time delay line for distributed coherent accumulation, and K4 high-speed photodetector for high-sensitivity reception of weak echoes. At the data processing end, K21 photonic reservoir computing technology is integrated for in-situ real-time calculation of marine environment parameters. Compared with traditional marine radar, the microwave photonic architecture gives the system THz-level instantaneous bandwidth, enabling simultaneous marine dynamic environment monitoring and maritime moving target detection, achieving integated sensing and communication (K8). Suitable for marine ecological early warning, maritime search and rescue, fishery resource management, marine disaster monitoring and other scenarios.
