PROBLEM TO BE SOLVED: To provide a position-detecting system capable of reducing errors caused by radiation directivity of radio waves. SOLUTION: This system is equipped with a transmission module 100 for detecting the detection azimuth in a prescribed detection, and radiating radio waves containing a signal of the detection azimuth; a plurality of receiving modules 200A, 200B, 200C arranged respectively on a plurality of reception positions, for receiving the radio waves; a temporary position calculating part 301 for calculating the temporary transmission position of the radio wave from a plurality of measured values of the radio wave intensities received by the plurality of reception modules 200A, 200B, 200C; a reception azimuth calculating part 302 for calculating each azimuth of the plurality of receiving positions, relative to the temporary transmission position; a radiation directivity storage part 401 for preserving the radiation directivity of the radio waves, based on the prescribed direction; a radiation directivity correcting part 303 for correcting the plurality of measured values, in the plurality of respective reception positions to the detection azimuth based on the radiation directivity; and a correction transmission position calculating part 304 for calculating the correction transmission position of the radio waves, from the plurality of corrected measured values on the plurality of receiving positions.
