A new near-field source parameter estimation method based on the combination array is proposed

which can provide the reliable prior information for the noise sources localization and identification.The form of the array is a uniform pressure sensor array

in whose center there is one three-dimensional vector hydrophone.By utilizing this combination array

the three-dimensional parameters of the near-field sources including the azimuth angle

the elevation angle and the distance can be achieved.This method only uses the second-order statistics information

and transforms the three-dimensional parameter estimation problem into several one-dimensional search problems

so it reduces the computational complexity and does not need additional parameter pairing algorithm.
