| Research Abstract |
In order to estimate lightning activities occurring within horizontal distance of 100 km, we have studied a single station lighting location technique. Additionally, we have developed a new portable lightning location monitoring system for an application of its single station lightning location technique. We have succeeded in the location accuracy improvement by using the information on time difference between the direct wave of sferics and the refection waves. We have developed a new wideband search coil magnetometer having two resonant frequencies for observation of sferics within 100 km. We have downsized analog circuits of a portable lightning location monitoring system by using an analog ASIC (application specific integrated circuit) preamplifier. These results could be important and useful for development of a new lighting monitor system by a single-station observation technique.
