| Abstract(in English) | In the interference source location system using satellites, the location of the interference source is determined from time difference of arrival (TDOA : Time Difference Of Arrival) and frequency difference of arrival (FDOA : Frequency Difference Of Arrival) between the multiple satellites. Since these location results include multiple interference sources, it is necessary to classify automatically for each interference source. Ward method and group average method are typical hierarchical clustering method and possible to classify even if the number of interference sources is unknown. In these methods, when the DOP (Dilution Of Precision) changes due to satellite movement, the error distribution of the positioning results changes, the variations in the positioning results increase, and it cannot be classified correctly. In this paper, we propose a clustering method ,that weights location results according to DOP determined by satellite position and interfering station position in the interference source location system. |
