Abstract
A train-position detection device includes: a radio-wave's angle-of-arrival calculator configured to calculate an angle of arrival of a radio wave on the basis of a reception signal received by an array antenna and a receiver; a position acquisition unit configured to acquire information on an installation position of a ground-based wireless communication apparatus from the reception signal; a train-position calculator configured to calculate a train position on the basis of a movement distance of a train; a correction-amount-to-train-position calculator configured to calculate a train-position correction amount, by using the calculated angle of arrival, the installation position of the ground-based wireless communication apparatus acquired by the position acquisition unit, and the calculated train position; and a train-position correcting unit configured to correct the calculated train position by using the train-position correction amount calculated by the correction-amount-to-train-position calculator.
