信号快速带通滤波方法在海洋信号分析中的应用

Fast Signal Band-pass Filtering Method and Its Application in Analyzing Ocean Signal

借助于离散"解析"信号提出了一种对信号进行快速滤波的方法。与传统方法比较,手续简单,快速有效,尤其适用复杂多变的海洋长信号的滤波。以2个典型信号的带通滤波为例,验证了快速滤波方法的有效性,2个复杂海洋信号的滤波结果表明,此滤波方法在海洋信号分析中有应用意义。

In this paper, a fast signal filtering method is suggested by means of discrete analytical signals. Compared with the traditional methods, this method is simpler in procedure, faster and more efficient in computation, and especially suitable for filtering the long ocean signal. The fast filtering method is validated by taking two band-pass filtering cases of typical signals as an example, and it is shown from the illtered results of two complicated ocean signals that the filtering method has applied significance the ocean signals.
