摘　　要：利用水下声信号的简正波传播特性,推导了一种利用垂直接收阵和已知宽带声源信号,对水下未知宽带声源进行距离估计的算法,即基于引导源的目标定位算法。该算法不需要建立精确的水下声场模型,且定位性能受海洋环境的影响较小。重点推导了算法实现过程,并简要介绍算法处理中的图像处理方法--Radon变换。对三组不同位置的声源,在不同海洋环境条件下进行了算法仿真。结果表明基于引导源的目标定位算法能快速、准确地估计出目标声源距离。An algorithm was deduced for estimating the range of an unknown broadband acoustic source in a wavegutae oy the orthogonality of the modes, using a vertical array and a signal sample from another broadband source at a known location to the array. The method requires no modeling of the acoustic field, and little to know environmental information for fiat bathymetris. The theory of the target localization algorithm using guide source （GTL） was detailedly introduced. The radon transform was introduced for processing the export image. And the algorithm was illustrated via simulation under varying ocean environments with range-independent bathymetries. The simulations are performed that the GTL algorithm can obtain an accurate target source estimate.
