摘要

摘要: 矢量水听器阵列优化设计、性能分析和信号处理系统仿真中, 需要知道阵列输出噪声的协方差矩阵等信息。分析了各向同性噪声场中矢量水听器的相关性, 得出了矢量水听器的自相关和互相关函数的一般表达式。结合概率分析, 给出了一种简单的各向同性噪声场的数值仿真方法。仿真结果表明, 文中所给方法产生的矢量水听器噪声的相关性与理论值吻合良好, 可为矢量水听器阵列的优化设计和矢量阵列信号处理系统的仿真分析提供准确的数值噪声。

Abstract: The covariance matrix of vector hydrophone array output noise is necessary in the array′s design, performance analysis, and simulation of signal processing system. We analyze the output correlation of the vector hydrophone in isotropic noise field and obtain the general formulas for auto-and cross-correlation between two vector hydrophones. With analysis of the probability, a simple method for numerically simulating isotropic noise field is proposed. Numerical simulation results coincide with the theoretical ones, which indicates the proposed method is effective and can generate accurate numerical noise for optimization design of vector hydrophone array and simulation analysis of its signal pro- cessing system.
