Abstract
A signal source specifying apparatus receives measurement results from a plurality of sensors that receive, from a plurality of signal sources, signals represented by vectors each having a predetermined direction and measure triaxial components orthogonal to each other to specify positions of the signal sources and the vectors. The signal source specifying apparatus includes a relational matrix recording section, and a position/vector deriving section. The relational matrix recording section records a relational matrix representing a relationship between the measurement results summarized per axis by a number of the sensors and the vectors. The position/vector deriving section derives the positions of the signal sources and the vectors that offer a minimum cost function based on the measurement results and the relational matrix. The positions of the signal sources and the vectors are specified based on a result of derivation by the position/vector deriving section.
