To provide a position detection system and a position detection method that can enhance the detection accuracy of unauthorized communication.SOLUTION: A first measuring unit 18a has radio waves transmitted in the order of a first communication apparatus 10 → a second communication apparatus 11 → the first communication apparatus 10, and measures a measurement value Dx related to propagation of the radio waves of first communication. A second measuring unit 18b has radio waves transmitted in the order of the second communication apparatus 11 → the first communication apparatus 10 → the second communication apparatus 11, and measures a measurement value Dx related to propagation of the radio waves of second communication. A correctness determination unit 20 determines whether the positional relationship between the first communication apparatus 10 and the second communication apparatus 11 is correct based on the measurement value Dx measured by the first communication and the measurement value Dx measured by the second communication.SELECTED DRAWING: Figure 1

    【課題】不正通信の検出精度を向上可能にした位置検出システム及び位置検出方法を提供する。【解決手段】第1測定部18aは、第1通信機10→第2通信機11→第1通信機10の順に電波を送信させ、この第1通信の電波の伝搬に係る測定値Dxを測定する。第2測定部18bは、第2通信機11→第1通信機10→第2通信機11の順に電波を送信させ、この第2通信の電波の伝搬に係る測定値Dxを測定する。正否判定部20は、第1通信で測定した測定値Dxと、第2通信で測定した測定値Dxとから、第1通信機10及び第2通信機11の位置関係の正否を判定する。【選択図】図1
