A location method for underwater explosion source and error analysis

Based on the minimum mean-square error approach, a computational method was proposed for locating the positions of underwater explosion sources. The verification experiments show that the proposed location method can meet with the test requirements when the quantity of the effective data observed by the pressure sensors is not less than four. Satisfactory computational results can still be obtained even if the accuracies of several test data are weak. The influencing factors of the computational error were discussed as follows: veracities of test data, position turbulence of test points, accuracies of model parameters and quantity of test points. Consequently, some suggestions were put forward about the location computation for underwater explosion sources.
