舰船水下噪声相干测量和分析的发展过程—单输入/单输出和多输入/单输出比较

Developmental Process for Coherent Measurement and Analysis for Underwater Noise of Ships -Comparison between Single Input/Single Output and Multiple Input/Single Output Cases

本文给出了舰船水下噪声测量和分析的发展过程，从单点测量发展为两点相于测量，构成对单输人／输出系统的分析；再从两点相干测量发展为多点互谱测量，构成对多输入／输出系统的多种分析。

The developmental process of measurement and analysis for underwater noise of ships is presented in this paper, in which the measurement of single point was evolved to coherent measurement of two points that relate to analysis of single input/ single output system, and coherent measurement of two points was evolved to coherent measurement of multiple points that relate to analysis of multiplw input /single output system.
