| description | To provide a transmitter search device with high search accuracy of the transmitter.SOLUTION: The search device moves from a first point to a first direction, and then estimates a present area of a transmitter from a change in a reception strength when moved to a second direction perpendicular to the first direction. The search device detects a second point different from the first point of the same strength as the receiving strength measured by the measurement unit at the first point. The search device moves from the first point to the first direction, and then estimates the present area of the transmitter from the change in the reception strength when moved to the second direction perpendicular to the first direction. Then, the search device determines the cross section of the first circle with a radius as the distance converted from the receiving strength measured by the measurement unit around the first point and the second circle around the second point with the radius as the distance in the estimated area.SELECTED DRAWING: Figure 5
【課題】発信機の探索精度が高い発信機探索装置を提供する。【解決手段】探索装置は、第１の地点から第１の方向に移動し、さらに当該第１の方向に対して直交する第２の方向に移動したときの受信強度の変化から、発信機の存在領域を推定する。探索装置は、第１の地点にて測定部で測定された受信強度と同じ強度が測定される第１の地点とは異なる第２の地点を検出する。探索装置は、第１の地点から第１の方向に移動し、さらに当該第１の方向に対して直交する第２の方向に移動したときの受信強度の変化から、発信機の存在領域を推定する。そして探索装置は、推定される領域において、第１の地点を中心としかつ第１の地点にて測定部で測定された受信強度から換算される距離を半径とする第１の円と、第２の地点を中心としかつ距離を半径とする第２の円との交点を、発信機の位置と決定する。【選択図】 図５ |
