Research on integrated positioning approach based on long/ultra-short baseline

With the development of underwater acoustic technology, the combination of multiple positioning means becomes the trend of underwater acoustic positioning technology. Based on an integrated long/ultra-short baseline location equipment, this paper discusses a multi-solution fusion method based on the minimum mean square error criterion. This method fuses long baseline and ultra-short baseline information on output, and it is relatively simple. The results of integrated long/ultra-short baseline location are compared with the results of long baseline location and ultra-short baseline location by simulation and experience. It shows that the integrated long/ultra-short baseline location system has the higher positioning accuracy than long baseline location and ultra-short baseline location. It realizes the high precision positioning of underwater target.With the development of underwater acoustic technology, the combination of multiple positioning means becomes the trend of underwater acoustic positioning technology.
