POSITION ESTIMATION DEVICE
PROBLEM TO BE SOLVED: To provide a technique for accurately estimating a position of the transmission source of the electric wave.SOLUTION: Acquisition means (S110) acquires a candidate direction serving as a direction where it is estimated that a transmission source of an electric wave is positioned, for each of n(n≥3) pieces of antennas based on the electric wave received. Estimation means (S150) estimates a candidate region as a region including a position of the transmission source of the electric wave with an arrival shaft which is a linear line extending to the candidate direction acquired by the acquisition means for each of N pieces of the antenna as an object and also with the region where the largest number of arrival shafts come to close to each other as the candidate region, the region being smaller than a predetermined allowable region.SELECTED DRAWING: Figure 2
【課題】電波の送信元の位置を精度良く推定する技術を提供する。【解決手段】取得手段（Ｓ１１０）は、Ｎ（Ｎ≧３）個のアンテナのそれぞれについて、受信した電波に基づいて、電波の送信元が位置すると推定される方向の候補となる候補方向を取得する。推定手段（Ｓ１５０）は、Ｎ個のアンテナのそれぞれについて取得手段により取得された候補方向に延びる直線である到来軸を対象として、最も多くの到来軸が互いに近づく領域であって所定の許容領域より小さい領域を候補領域として、該候補領域を電波の送信元の位置を含む領域であると推定する。【選択図】図２
