【摘要】 本文在自适应LMS算法的基础上,引入Kalman滤波方法探讨对地震前兆资料中畸变的消除及对信号的恢复。本文对一个人为构造的信号进行了试算,取得了极为满意的结果,其原信号和恢复后的信号间的互相关系数达到99.9％,同时对在山东莒县记录到的地声信号进行了处理,亦得到了很好的结果。更多还原

【Abstract】 Based on adaotive LMS algorithm, the method of Kalman filter is induced to study how to cancelthe distortion in the seismic precursory observation data and how to recover the signal.The paper calculate an artifical signal. The result is satisfactory. The coefficient between the original signaland recovered signal is 99.9%. The good result is got by processing the geosound signal recorded in Juxian Coun-ty, Shandong province.更多还原
