水中目标回波亮点时空相关与脉间相关特性研究

Study on Spatial-Temporal Correlation and Pulse-Pulse Correlation Feature of High Frequency Echoes From Underwater Target

信号相关分析是时域和空域中一种基本的、但又是重要的信号分析方法。本文介绍了水下目标回波时空相关特性分析和脉间相关特性分析的基本原理 ,并给出了高频回波测试系统获取的海试数据的处理结果。

Signal correlation analysis is a basic as well as an important method that owns wide applications in data processing in time domain and space domain. In this paper, the basic principle of spatial-temporal correlation analysis, and pulse-pulse correlation analysis method to the underwater target echo are introduced. The process result of echoes acquired by the 'High Frequency Target Echo Measurement System' is also presented.
