PROBLEM TO BE SOLVED: To improve reliability of estimation results in position estimation of a detection target.SOLUTION: A position estimation system is designed to estimate a position of a detection target on the basis of a radio signal received in a building with a plurality of allocated areas. The position estimation system detects the detection target using a radio signal received by a receiver, and translates a detection result of a position of the detection target into a position information probability for each of the areas.SELECTED DRAWING: Figure 1 【課題】検出対象の位置の推定における推定結果の信頼度を高める。【解決手段】位置推定システムは、複数の領域を割り当てた建物において、受信した無線信号に基づいて検出対象の位置を推定する。位置推定システムは、受信部により受信した無線信号から検出対象を検出し、前記検出による検出対象の位置検知の結果を、前記領域毎の位置情報確率にする。【選択図】図１
