摘要/Abstract

摘要： 为了解决近场被动目标的三维定位问题，在多途条件下提出了一种水平阵定位方法。任意选择扫描深度获得二维声图测量结果，进而在二维扫描平面搜索谱峰，得到目标信源与海面镜像虚源的聚焦点位置；利用它们的几何关系对测量结果进行修正，得到目标的三维坐标。仿真结果表明：不同的扫描深度对定位精度的影响较小；随着目标远离阵列，定位误差逐渐增大；在靠近阵列的区域里，多途聚焦点与直达声聚焦点混叠，方法失效。因此，该方法可以在多途条件下对一定范围内的近场被动目标实现三维定位。

Abstract: A localization method based on the horizontal array in a multipath environment is presented for three-dimensional passive localization of near-field source. The result of underwater acoustic image measurement is obtained in an arbitrary scanning depth, and then the focal points of the signal source and the virtual source formed by surface reflection could be located by spectral peak searching. The three-dimensional coordinate is corrected by the geometric relationship of the focal points. The simulation shows that the different scanning depths have little impact on localizaton accuracy, the localization error increases with further distance between the source and the array, and the method is invalid when the source is much closer to the array because of aliasing in the two focal points. The method could three-dimensionally localize the near-field passive source within a certain region in a multipath environment.

Key words: information processing, horizontal array, multipath channel, three-dimensional passive localization
