卡尔曼滤波压制瞬变电磁干扰技术及应用
Technology of suppressing TEM interference by Kalman filtering and its application in detection of goaf in coal mine
摘要
Abstract
Coal transient electromagnetic exploration is often conducted around a coal mine where man-made in-terference is stronger, noise in a secondary induction field signal is mostly higher, it is difficult to carry out proc-essing and interpretation. In order to eliminate these electromagnetic interference in data, according to the mor-phological characteristics (One-way attenuation) of decay curve, by Kalman filtering method, suppressing inter-ference can be quick and easy, and the original signal is better restored. By using this method to process and inter-pret the actual data affected by electromagnetic interference of high voltage line, comparison of data after filtering with data collected after power off of high voltage line, data have been basically consistent, demonstrating that the method is effective.关键词
