摘要
文章主要介绍了AR模型及其参数确定的基本方法。应用Matlab仿真软件,对海洋环境噪声信号的时间序列进行仿真分析,并对预测值与真实值进行比较。结果表明,应用AR模型预测得到的环境噪声信号很好地逼近了实测值,预测的功率谱也具有较高的精度,模拟的结果较好,为海洋环境噪声的预报提供了一种简单可行的模式。
AR model and methods of parameters confirming are introduced. The simulation of the ambient noise signal is conducted using Matlab. The results are compared with actual value. The results indicate that the output of this method is precise in both time field and frequency field, which provides a simple means for the forecast of the ambient noise in the sea.
