Kalman滤波在地震电离层TEC异常探测中的应用
|
摘要
基于中国地壳运动观测网络GPS观测资料解算的电离层TEC数据,利用Kalman滤波方法对2008年5月12日汶川Ms8.0地震前的电离层TEC进行异常探测研究,并与以前的处理结果进行对比,对比结果表明:利用Kalman滤波方法能够有效地探测到震前的电离层TEC异常扰动。
It has been verified by plentiful existing observations that the ionospheric disturbance do appear prior to earthquake.In this paper,on the basis of the ionospheric TEC derived from the GPS observation data from the reference stations of Crustal Movement Observational Network of China,we processed and analyzed the ionospheric TEC data prior to the WENCHUAN Ms8.0 earthquake by Kalman filtering and then we compared the results with the previous conclusion,the results indicate that the establishment of the model of the Kalman filter is reasonable and reliable in the detection of the ionospheric TEC anomaly prior to earthquake effectively.
