| Abstract(in English) | The measuring system for electromagnetic noise had been constructed by us. And many noise spectrum datas has stored by the measuring system. For automatic measurement (hand free measurement ), the measuring system modified. The analysis tool is constructed from GUI(graphic user interface) so that many stored datas can be easily analyzed. We study about noise spectrum features as compared with weather conditions. Noise spectrum features almost appear in less than l50MHz. Noise spectrum levels almost low in rain and snow conditions. Noise spectrum levels become high, according as frequency become low, less than 150MHz in fine weather. Noise spectrum levels are very high less than 100MHz in thunderstorm weather. |
