自适应滤波器在地磁数据噪音处理中的应用

利用自适应信号处理的原理，尝试消除地磁观测数据中的干扰噪音。结果显示这种方法能有效地抑制包括随机噪音，大幅度突跳偏离和阶跃各种形式的干扰。对于和信号频率相重的干扰能给予有效抑制，且能保持信号基本不变。

The use of adaptive filter for noise Processing on geomagnetic

Using the Principle of adaptive data processing,an experiment to eliminate the dis-turbance noise in the geomagnetic observation data was made. The resuIts show that themethod can effectively depress various of disturbances,such as random noises,spikesand steps. The noises with the same frequencies as signal can also be depressed effec-tively,and the signal can almost not be changed.
