Zusammenfassung:	A train-position detection device (1) includes: a radio-wave's angle-of-arrival calculator (14) configured to calculate an angle of arrival of a radio wave on the basis of a reception signal received by an array antenna (11) and a receiver (12); a position acquisition unit (13) for a ground-based wireless communication apparatus, configured to acquire information on an installation position of a ground-based wireless communication apparatus (30) from the reception signal; a train-position calculator (15) configured to calculate a train position on the basis of a movement distance of a train (40); a correction-amount-to-train-position calculator (16b) configured to calculate a train-position correction amount, by using the radio wave's angle of arrival calculated by the radio-wave's angle-of-arrival calculator (14), the installation position of the ground-based wireless communication apparatus (30) acquired by the position acquisition unit (13) for a ground-based wireless communication apparatus, and the train position calculated by the train-position calculator (15); and a train-position correcting unit (17) configured to correct the train position calculated by the train-position calculator (15) by using the train-position correction amount calculated by the correction-amount-to-train-position calculator (16b).
