Abstract:

The measurement of the position of the impact point at sea is a key step in the precision test of naval gun weapons in the sea shooting range. It is of great significance for the construction of the shooting range and the improvement of the combat effectiveness of the army. The passive acoustic detection technology is used to improve the array arrangement mode based on the single three-element array positioning, and a marine impact point positioning method based on dual cross-array is proposed. The positioning principle is deduced and described, with emphasis on the detailed error analysis and simulation of three-element array positioning and dual cross-array positioning. Finally, it is concluded that under the ideal example assumed in this paper, the positioning error of the impact point positioning method based on dual cross-array is reduced to 4.66‰ of that of the single three-element array positioning method, which better meets the requirements of impact point positioning at sea, and has a certain application value and development prospect.

Key words: location of impact point at sea, sensor array, dual cross-array, underwater acoustic passive location, error analysis and simulation
