Abstract
To realize the positioning of underwater sound sources, a target positioning method based on acoustic field HBT interference is proposed. The precision of HBT interferometric target locating principle is verified by simulation under different parameters. The positioning effect is simulation analyzed at different frequencies with multiple sound sources. The results show that the position of the sound source can be found accurately by this method for single frequency source and multiple sources. At the same time, the positioning experiment in lake is carried out. The results verify the correctness of HBT positioning method and realize the orientation of single and multiple frequencies with the level of 180 dB which the distance of the sound source is 59 meters.
