Embodiment 2

[0032] The invention relates to an underwater positioning system, especially a set of target simulator software system close to the ocean environment is designed based on LabVIEW, and a target simulator hardware system is designed based on the OMAP-L138F core board.

[0033] In recent years, with the continuous development of marine science and technology, underwater positioning technology has become an important topic. The development of underwater positioning technology plays an important role in the development of my country from a large ocean country to a powerful ocean country. In the past, large-scale hydroacoustic positioning equipment required a large number of underwater experiments to test the performance of the equipment before delivery. However, conducting underwater experiments is costly. In order to reduce the expenditure of manpower and material resources, electric simulators came into being. According to the propagation characteristics of the target in the oc...

Description

technical field [0001] The invention belongs to the field of underwater positioning, and in particular relates to an electric simulator applied to an underwater positioning system. Background technique [0002] In recent years, with the continuous development of marine science and technology, underwater positioning technology has become an important topic. The development of underwater positioning technology plays an important role in the development of my country from a large ocean country to a powerful ocean country. In the past, large-scale hydroacoustic positioning equipment required a large number of underwater experiments to test the performance of the equipment before delivery. However, conducting underwater experiments is costly. In order to reduce the expenditure of manpower and material resources, electric simulators came into being. According to the propagation characteristics of the target in the ocean, it simulates the received signal in the real ocean enviro...
