摘要
本文采用小波变化分别对受磁扰时段的"天宫一号"大气质谱信号和乌鲁木齐台地磁FHDZ-M15秒数据进行频段分析.实验发现"天宫一号"大气质谱信号和地磁M15秒数据信号的频谱优势频段在0.005~0.025 Hz之内,其中主要受干扰的频段为0.01~0.02 Hz.在地磁M15秒数据的预处理数据中,将H分量和F分量的主要磁扰频段滤出,实验结果表明:含有主要磁扰频段的H分量和F分量SNR(信噪比)分别为37.17 d B和32.99 d B,滤出空间主要磁扰频段后的H分量和F分量SNR分别为215.71 d B和245.54 d B,SNR有了很大的提高.地磁M15秒数据信号有了较为明显的改善,提高地磁资料对于地震监控的应用效果.
This paper analyzed geomagnetic disturbance frequency bands using wavelet method about Tiangong-1 atmospheric spectrum signals data and geomagnetic M15 second data. We found the dominant frequency bands was 0. 005 ~ 0. 025 Hz,and the major interference frequency was 0. 01 ~ 0. 02 Hz. In the experiment,we filtered out main interference frequency from the Horizontal component and Magnetic field strength of geomagnetic M15 second data. The experiment results show that H component of SNR( signal-to-noise ratio) was 37. 17 dB that containing the main magnetic interference frequency,and F component of SNR was32. 99 dB that containing the main magnetic interference frequency.However,H component of SNR was 215. 71 dB and F component of SNR was 245. 54 dB when we filtered out main interference frequency in the experiment. SNR has greatly improved. Geomagnetic M15 second signal in the experiment has more significant improvement,improved the effect of geomagnetic signal for earthquake monitoring application.
