本文介绍一种信息处理的方法——二阶谱法。简单阐述了该方法的基本原理,以及在PS计算机上实现这个方法的基本步骤与程序,最后用该方法处理了地声信息。结果表明,处理后的信噪比有显著的提高。
This article describes a method of information processing - second-order spectral method. The basic principle of this method is briefly described, and the basic steps and procedures of this method are implemented on the PS computer. Finally, this method is used to process the geophone information. The results show that the signal to noise ratio has been significantly improved after treatment.
