The "Data Voyage" of a naval force: Kang Zizhan, a reporter from the People's Liberation Army Daily, Gao Liang, a correspondent, Du Yu, Wang Zezhou, a naval detachment of the Northern Theater Command, organized a fleet of ships to conduct practical training in a certain sea area. Wang Zezhou keeps his combat data up-to-date every battle, and whenever the ship returns from training, it is the busiest time for data analysis technicians from a certain detachment of the Northern Theater Command Navy. As data analysis technicians, their main job is to collect various types of data brought back by each ship of the detachment during each sea training, and analyze and compare these data in a timely manner, archiving and storing useful data. The underwater acoustic data in recent years has been stored in hard drives and specially classified. These large capacity hard drives are the "precious lumps" of analysis technicians - they store the underwater acoustic data collected during the training of various ships in the detachment in recent years, which is a database they have created for the sonar profession for many years. Underwater attack and defense is a major challenge for naval naval forces in deep sea operations, and underwater acoustic target signal reconnaissance and discrimination are the foundation for improving underwater attack and defense capabilities. In order to improve the level of underwater acoustic data collection and organization, data analysis technicians collect data extensively before each ship's departure, carefully study the characteristics and laws of the underwater acoustic environment, and develop suitable underwater acoustic reconnaissance plans, At the same time, data collection training is also conducted for sonar soldiers performing tasks. In the military field, data is also known as the 'blood of information systems', and the sharing, integration, and distribution of data can stimulate the vitality of the combat system. In the view of a data analysis technician, these data contain the' password 'that leads to victory. As a radar soldier, he realized the value of data during training as early as this data analysis technician joined the army. At that time, each radar soldier would encounter various targets with different attributes in their missions, and each had their own "discrimination manual", but such experiences could not be accurately shared. Therefore, this data analysis technician has a wish: how convenient would it be to have a large database that can sort, summarize, exchange, and share all the previously detected target information. What he didn't expect was that over the years, this wish not only gradually became a reality, but he also became a well-known data expert in the team. A piece of underwater acoustic data may be the golden key to opening the 'door to victory' of a battle, "said the data analysis technician. One of the key tasks in each training session is data collection, which is deeply ingrained in our team's hearts. "Regarding the perspective of this data analysis technician, the head of a certain naval vessel department of the team deeply felt. As one of the first crew members of the People's Navy's first 10000 ton large displacement Nanchang ship, this department head still remembers the scene: that year, he and his comrades carried out the first live fire mission of the Nanchang ship's main gun. When the shell burst out and successfully hit the target, a sense of mission arose in his heart. At the review and summary meeting, the department head said, "We will complete the first live fire of the main gun of the 10000 ton drive, and record the first set of shooting data. From now on, we will maintain a good attitude towards writing the first chapter of ship history and record the data of each live fire. This is to lay the foundation for understanding the 'temperament' of our weapons and also to leave behind for future generations
