| Abstract: | The seimo-electromagnetic radiation observation is important for short - impending prediction. The feasibility and necessity of a digitized observation system on a PC as its core is probed in this paper, and the design method of a practicable system is given. Digitized systems have the advantages of high sensitivity, in favour of not only observing signals real - time analyzing and recognizing, and short - impending prediction information extracted by using algorithms, but also data transmission and processing within observing networks. Based on observed signals analysis and comparison in time - domain and frequency -domain, the method of distinguishing interfere signals and abnormal electromagnetic radiation signals Is given. |
| Keywords: | Short -impending prediction Electromagnetic radiation Digitize Signal recognition |
