模式匹配法水下目标定位仿真研究

Study on Simulation of Matched- mode Processing for Underwater Locating

匹配场处理是一种水声学和物理学相结合的信号处理技术,其在水下目标定位方面的高精度特点使得该方法受到广泛关注。匹配模处理是工作在模态空间的匹配处理方法。介绍了匹配模处理的基本原理,并通过仿真实现匹配模处理方法。通过对同一目标声源的定位,得到匹配模处理方法的性能优于匹配场处理方法。

Matched -field processing,combining with underwater acoustics and physics,is a signal processing technology and is popular as the characteristics of high precision underwater target localization. Matching -mode processing is a matched processing working in mode space.Its basic principle is intro-duced in this paper and the method is implemented by simulation.By locating the same target sound source,the performance of matched -mode processing is better than that of matched -field processing.
