| Abstract: | A group of ultra-low frequency electromagnetic radiation observation network has been built in the Capital circle region since 1982. The network is mainly used to observe electric field change by electrode under the ground. At the same time, it is used to accept magnetic sign. Using some techniques, such as the selected observation frequency band, deep-buried electrode, filtering of waves etc, can reduce the interference. Some possible effects of related factors are studied and the classification and processing methods of anomalous figures are given in the recorded data. |
