中文摘要：

为了避开传统的匹配场目标定位技术对环境先验知识的依赖性，提出了在均匀浅海环境中只知道少量环境参数的情况下，利用垂直接收阵和不同距离上的两枚宽带引导声源重构声场对目标声源进行定位的一种方法。这种方法主要基于简正波估计和声场重构两种关键技术，同时省去了匹配场定位技术中大量的拷贝声场计算。数值仿真主要采用线性Bartlett匹配处理器分析了目标定位效果，在信噪比高于10dB的情况下，定位效果良好。

英文摘要：

A new method of object source localization, on the condition that a few environment parameters are known in range-independent shallow water environment, by using the vertical receiver array and the broadband guide source to reconstruct acoustic field, is presented to avoid the strong dependence on environment parameters of traditional matched field processing localization technique. This method is mainly based on normal modes estimation technique and acoustic field reconstruction technique and also can avoid the complicated computation of replica field for matched field processing localization. Linear Bartlett processor is used to analyze the simulation results. Desired results are obtained when the signal-noise ratio is higher than 10 dB.
