地震动信号的分析与目标识别
Seismic Signals analysis And Identification
摘要
Abstract
Great deals of signals obtained from field-testing have been processed in time andfrequency domain with Short Time Fourier Transform and wavelet package transform techniques. On thebasis of far distance seismic signal, target recognition has been made by BP neural network, the resultindicates that the recognition ratio is as high as 85 % on the eigenvector of wavelet package decompose,and shows that the eigenvector of wavelet package decompose has better performance.关键词
