为了克服传统信号处理方法对地震反射信号这一类非平稳信号的局限性,本文通过利用小波变换中奇异信号和随机噪声在多尺度空间中不同模极大值的传播特性设计的于波消噪方法,对模拟地震信号处理的仿真结果表明小波方法在处理地震信号等一类非平稳信号时能获得较好的信噪比增益,保持对突变信息的良好分辨率。
In order to overcome the limitation of the traditional signal processing method to the non-stationary signal such as seismic reflection signal, this paper, by using the de-noising method designed by using the propagation characteristics of different modulus maxima of singular signal and random noise in multi-scale space The simulation results of simulated seismic signal processing show that the wavelet method can obtain a good signal-to-noise gain while dealing with a class of non-stationary signals such as seismic signals and maintain a good resolution of the abrupt information.
