Abrégé

This position detection device is mounted on a moving body to detect the position of an object. The position detection device comprises: a sensor unit which transmits electromagnetic waves, receives reflected waves from objects around the moving body, and measures the position of the reflection point in which the electromagnetic waves are reflected, at predetermined intervals, on the basis of the received reflected waves; a storage unit which stores position data indicating the position of the reflection point for each cycle measured by the sensor unit as a frame of the cycle interval; a search range determination unit which determines a search range on the basis of movement information indicating the movement of the position detection device; and a noise identification removal unit which identifies noise contained in position data on the basis of the determined search range, removes the identified noise from the position data, and uses the noise-removed position data as position data indicating the position of the object.
