说明：  浅层海洋环境由信源组成声源，海洋形成信道，和水听器阵列组成接收器。在这个传播模型中，信源，信道和接收信号这三者，通常能知二求一，具体应用诸如利用海洋环境参数和接收到的信号来定位声源，或者通过计算发射信号和接收信号之间的差异，反演海洋环境参数。 而在接收器方面，我们通过设置各向同性的水听器阵列。通过算法和处理器，我们便能量化模型，传统是处理器主要基于接收信号是高斯信号，而海洋中存在着大量的有色噪声。本课题的研究目的便是在前人的基础上，在海洋声层析成像的背景下，在信源与接收器阵列之间，引入信号的高阶统计量，对非高斯过程的水下信号源进行定位，并提高算法的性能和准确性。 利用非高斯过程的高阶累积量不恒为零的特点，滤去高斯有色噪声对信号的影响，其又包含了信号的相位信息，便可以极大的优化匹配场处理过程的性能和准确性。(After receiving signals based on high order cumulant matched field processor after matched field localization, the positioning effect will be more accurate, sidelobe suppression more effectively, and compared with other traditional matched field processor in low SNR environment, it can position more accurately.)

　20世纪70年代，美国新墨西哥大学计算机科学系主任Cleve Moler为了减轻学生编程的负担，用FORTRAN编写了最早的MATLAB。1984年由Little、Moler、Steve Bangert合作成立了的MathWorks公司正式把MATLAB推向市场。到20世纪90年代，MATLAB已成为国际控制界的标准计算软件。 (70 years of the 20th century, the United States Head of the Department of Computer Science, University of New Mexico Cleve Moler in order to reduce the burden of student programming, the earliest written with FORTRAN MATLAB. 1984 by Little, Moler, Steve Bangert cooperation established in the MathWorks MATLAB to market the company officially. 90 20th century, MATLAB has become the international control of industry standard calculation software.)
