Abstract:
The present invention can improve the precision of location estimation of a signal transmitting source. This location estimating apparatus is provided with: a data acquisition unit for acquiring measurement values of sensors which measure radio waves of a signal transmitting source and location information on the sensors; a class classification unit for class-classifying the acquired measurement values by using relative locations and the dissimilarity of the measurement values of each set of the sensors; and a location estimation unit for estimating the location of the signal transmitting source on the basis of the classified measurement values and the location information of the sensors.
