Abstract

A new method of target localization based on two broadband guide sources is presented, using which only few environment information need to be known in range-independent shallow water environment. This method, based on warping trasnsform, calculates the replica field by calculating the position information and phase information of the field, respectively. Also, compared with the traditional Matched Field Processing localization method, it can avoid the dependence on environment parameters and the field model. Accurate localization results are obtained when the Signal-Noise ratio is higher than 15dB and the range of the target is less than 20km.

基于两种宽带导频源的目标定位

提出了一种在距离无关的浅水环境中只需要少量环境信息的基于两个宽带导引源的目标定位方法。该方法基于翘曲变换，分别通过计算场的位置信息和相位信息来计算复制场。同时，与传统的匹配场定位方法相比，该方法可以避免对环境参数和场模型的依赖。当信噪比大于15dB，目标距离小于20km时，可获得准确的定位结果。

期刊介绍： Currently known as Journal of Theoretical and Computational Acoustics (JTCA).The aim of this journal is to provide an international forum for the dissemination of the state-of-the-art information in the field of Computational Acoustics. Topics covered by this journal include research and tutorial contributions in OCEAN ACOUSTICS (a subject of active research in relation with sonar detection and the design of noiseless ships), SEISMO-ACOUSTICS (of concern to earthquake science and engineering, and also to those doing underground prospection like searching for petroleum), AEROACOUSTICS (which includes the analysis of noise created by aircraft), COMPUTATIONAL METHODS, and SUPERCOMPUTING. In addition to the traditional issues and problems in computational methods, the journal also considers theoretical research acoustics papers which lead to large-scale scientific computations. The journal strives to be flexible in the type of high quality papers it publishes and their format. Equally desirable are Full papers, which should be complete and relatively self-contained original contributions with an introduction that can be understood by the broad computational acoustics community. Both rigorous and heuristic styles are acceptable. Of particular interest are papers about new areas of research in which other than strictly computational arguments may be important in establishing a basis for further developments. Tutorial review papers, covering some of the important issues in Computational Mathematical Methods, Scientific Computing, and their applications. Short notes, which present specific new results and techniques in a brief communication. The journal will occasionally publish significant contributions which are larger than the usual format for regular papers. Special issues which report results of high quality workshops in related areas and monographs of significant contributions in the Series of Computational Acoustics will also be published.
