摘要：

A data fusion localization algorithm for bistatic sonar based on the single vector transducer is proposed. The principle and implementation scheme of the data fusion localization algorithm for the vector bistatic sonar are presented. Compared with the common T/R-R bistatic sonar systems in the pressure acoustic field, vector bistatic sonar systems can obtain more information of the acoustic field. Compared with the time only location (TOL) localization algorithm based on the traditional pressure sensor, the new algorithm can obtain a higher localization accuracy. In the triangle zone near the baseline, the new algorithm can increase the localization accuracy by 23%, and in the blind zone near the baseline, that can be increased by 40%. Moreover, it can also resolve the localization ambiguous problem of the TOL algorithm.
