Chinese submarines equipped with underwater acoustic identification to identify the target is no longer rely on the ear
the original text with map: Cheng Yusheng field testing of underwater acoustic equipment, submarine polish “eyes”
the East China Sea waters, simmering. Hunting undersea in a submarine at the moment with its “eyes and ears” – sonar to capture traces of the surface battlefield. “Found an unknown target!” Sonar, the report of the soldiers, so that the narrow cabin air suddenly solidified.
in sonar soldiers concentrate discriminant goal of nature, a face lean navy colonel turned his gaze away from a device, calm and firmly say: “It is the Merchant Shipping.”
Shortly after, the the sonar soldiers confirmed that “the merchant”. People can not help but admire the sights of the Navy colonel – our army of well-known sound of water experts, Naval Submarine School Professor Cheng Yusheng. Cheng Yusheng and colleagues 10 years of tireless research, underwater acoustic target recognition internationally recognized technical problems on a breakthrough in the successful production of a certain type of acoustic equipment, so that Chinese submarines cruising in the deep sea, from With “smart ear” clairvoyance. ”
submarine force, there is a saying, “Sailing the Seas Depends sonar. Underwater sound is the only medium of submarine target identification. The traditional means of identification rely mainly on sonar soldiers artificial sentenced to listen, with experience, but this experience to rely on the accumulation of years of post. A submarine detachment of an old sonar soldiers had described his past the embarrassment: Times a heart hair is true, the target can not be determined in the end is what can not give the commander accurate information.
the face of the needs of the submarine forces of information warfare, in the face of the submarine officers and men the hope of technological change in their prime, Cheng Yusheng took a “monk” for scientific research.
At that time, the underwater acoustic identification problem has attracted the attention of the domestic scientific community, a number of universities and research institutes are conducting research, Naval Submarine Academy as a command schools, there is no advantage at all. Leadership kindly reminded Cheng Yusheng: the risk of doing this project, it may do no result. “
” Since it is restricting the construction of naval combat effectiveness of the ‘bottleneck’, we must dive down to overcome. “Huai Cheng Yusheng submarine force, love, took years of research topics of this shelving.
However, the reality is constantly confirms everyone’s fears. Since this study is carried out, Cheng Yusheng have not been winning achievements appear originally in the College of high-profile, he gradually fade out of people’s vision. More than 3000 days and nights, Cheng Yusheng sleepless nights, immersed in complex research.
this silence is 10 years, Cheng Yusheng group led by silently in a scientific cliff climbing straight up, and finally achieved initial research, in November 2007, the submarine recognition equipment model development work is completed to become the country’s first underwater acoustic target recognition equipment.
Cheng Yusheng has a habit of every time the submarine force, travel, will bring the number of unknown target noise signal, freeing up time and sonar technicians to exchange views and learn. He said: “to engage in research not only want to grant a man a fish, but also need to delegate to fish.”
the same CT films, and sometimes only a skilled doctor can see that illness. “This is Cheng Yusheng so often In the mouth the sentence. He said the equipment installation on the submarine, their task is not yet complete, only the officers and men in order to truly combat. Submarine voyage back, he was always the first call to inquire about equipment usage.
always forces demand for the purpose of Cheng Yusheng led to the development of a discipline, influence and train a group of people: more than 10 faculty that everyone has a teaching and scientific research, all of them based on their own to become the sound of water sector celebrities, the center of the sound of water was named the army learning to become model units, and promote the reform of the training methods of the submarine force.
