A research team from Donghai Laboratory — located in Zhoushan, Zhejiang province — has successfully conducted the first sea trial of the world's first fully anti-interference ocean radar, according to Tide News on Dec 12.

The trial — carried out near Dongji Island in Zhoushan — overcame challenging conditions, including strong waves and limited visibility. Despite water clarity allowing only 2 meters of visibility, the radar accurately measured depths of nearly 50 meters. 

Researchers noted the technology's potential to exceed 100 meters in clearer offshore waters, marking a significant breakthrough in oceanic sensing technology.

The radar, developed entirely in-house at Donghai Laboratory, addresses a longstanding global challenge — laser radar's susceptibility to environmental light interference. This innovation enables continuous, all-weather monitoring of both atmospheric and marine conditions, paving the way for advancements in remote sensing.

Established just two years ago, Donghai Laboratory has achieved this milestone as part of its focus on marine environmental sensing. As one of Zhejiang's 10 key provincial laboratories, it aims to advance intelligent marine sensing technologies, engineering applications, and industrial transformation.
