Abstract:

The double pulse sources method (DPS) is used to estimate the track of the high speed underwater vehicle. The linear track parameters and the speed at each time will be achieved based on the direction estimated by two CW pulse reference sources, the emitted and recorded time of each pulse front, and the dual-source distance which is known in advance. Simulation results show that the DPS method improves the performance of the traditional source estimation reference method. In the reservoir simulation experiments, the deviation of direction estimation is less than 1% and the deviation of distance estimation is controlled to within 9% by the DPS algorithm. The DPS is suitable for underwater vehicle track estimation.
