In order to increase the operation distance of passive self-homing and the parameter estimation precision for the target efficiently,the methods of information fusion with multi-array are adopted for the underwater vehicle.From the aspects of waveform level fusion and beam level fusion,simulation experiment studies is carried through the passive localization methods for the target with multi-array.And the statistical performance analyses of different fusion methods are provided.The simulation results show that,the localization precision for the target is improved efficiently with information fusion of multi-array,and the detection capability outperforms from 1 dB to 3 dB.So the efficient operation distance of passive self-homing is enhanced.
