1.1 Strategic Setting: The Technological Iteration and Industrialization Year of Deep Sea Technology in 2026At the beginning of the 15th Five Year Plan, the wind direction completely changed. In the past, deep-sea technology was seen by many as a "bonsai" in the laboratory, beautiful but far from money. 2026 is a watershed year. The national strategy includes the deep sea as an emerging industry, with a clear intention: this field must shift from scientific research and exploration to large-scale applications. This is no longer an era where you can simply submit a few papers.The keywords for 2026 have been reduced to two: technological iteration and industrialization. Why is it technical iteration? Because the extreme environment of the deep sea is heartless. For every 1% increase in reliability, costs may drop significantly. Why industrialization? Because having a...

Core data of this article:The development of China's sonar industry; The demand structure of China's sonar industry; Future ProspectsIntroduction and Early Development: Introducing Soviet Sonar TechnologyDuring World War I, in order to detect submarines hidden underwater, the famous French scientist Langevin developed piezoelectric transducers and used the newly emerging vacuum tube amplification technology to detect long-range targets in water. He received the echo of submarines for the first time, pioneering modern acoustics and inventing sonar in the true sense. He utilized the piezoelectric effect of quartz to develop a device capable of generating and receiving ultrasonic waves, laying the foundation for the practical application of sonar technology. Chinese sonar technology has developed rapidly in recent years and has been widely applied in various fields su...

At the recent Yangtze River Delta International Emergency Expo, Ningbo Bohai Shenheng Technology Co., Ltd. made a heavyweight appearance with multiple independently developed underwater imaging sonar equipment, bringing breakthrough solutions to emergency rescue, deep-sea exploration and other fields, attracting widespread attention in the industry.As is well known, water rescue sonar is crucial in the field of emergency rescue. With sound wave detection technology, it can penetrate complex turbid and dark water environments, quickly and accurately locate targets such as drowning victims and sunken ships, effectively break through blind spots in underwater detection, and greatly improve search and rescue efficiency; At the same time, sonar can significantly reduce operational risks by drawing underwater topographic maps in advance and marking hazardous areas, avoiding dir...
