浅水波导中的三维高阶光路分离
Three dimensional higher-order raypath separation in a shallow-water waveguide
摘要：
由于浅海环境中存在的色噪声和多径射线之间的相互干扰，特别是当两条射线到达距离较近时，分离多径射线是一个具有挑战性的问题。因此，在本文中，提出了一种三维（3D）阵列阵列配置中的高阶射线路径分离。通过对多径环境下的仿真数据、超声波波导中的实际数据和海洋浅海数据的性能测试，表明该算法与现有算法相比具有更高的分辨率和更强的鲁棒性。
英文摘要：
Separating raypaths in a multipath shallow-water environment is a challenge problem due to the interferences between them and colored noise existing in ocean environment, especially for two raypaths arrive close to each other. Thus, in this paper, a three dimensional (3D) higher-order raypath separation in an array to array configuration is proposed. Performance tests using simulation data in a multipath environment, real data obtained in an ultrasonic waveguide and ocean shallow-water data, respectively, illustrate that the proposed algorithm achieves a higher resolution and a stronger robustness comparing to the existing algorithms.
