摘要
舰船作为一种军民两用的交通工具,既是一种重要的交通运输工具,又是一种重要的军事装备。不论是在民用领域,还是在军用领域,都需要对水下信号进行检测和识别。由于电磁波在水中传播的干扰较大且衰减较快,电磁波在水下通信领域的应用较少。现在普遍采用声波作为水下通信的主要方式,本文对水声通信系统及对相关检测技术进行仿真分析,验证相关检测技术在水下信号识别中的应用价值。
The ship is a kind of dual - use vehicle, which is a kind of important traffic tool and also an important military equipment. Whether in civilian areas, or in the military field, the underwater signal detection and recognition are required. Because the shortcomings of the large seawater interference and rapid attenuation of electromagnetic wave, the electromagnetic wave is less used in underwater communication applications. The acoustic wave is now widely used as a main mode of underwater acoustic communication, this paper carried on the analysis on the underwater acoustic communication system, and analyzed the correlation detection technique, and the completed the simulation analysis, verified the correlation detection technique has certain value of application in underwater signal recognition.
