Zusammenfassung: | To provide a technique for calculating reception strength accurately, while taking account of measurement accuracy of an actual measurement value.SOLUTION: In a reception strength calculation device, an actual measurement value acquisition unit 62 acquires an actual measurement value of reception strength, when receiving radio waves transmitted from an origination point at a plurality of respective actual measurement points. A theoretical value acquisition unit 60 acquires a theoretical value of reception strength at a reception point corresponding to each of the actual measurement values of a plurality of reception strength acquired by the actual measurement value acquisition unit. A derivation unit 38 derives difference between the actual measurement value of reception strength and the theoretical value of reception strength, at each actual measurement point, on the basis of a plurality of actual measurement values of reception strength, and a plurality of theoretical values of reception strength. An object point theoretical value acquisition unit 64 acquires the theoretical value of reception strength at a reception point becoming an object of reception strength calculation. A correction unit 36 performs correction for the theoretical value of reception strength acquired by the object point theoretical value acquisition unit, on the basis of the difference at each actual measurement point.SELECTED DRAWING: Figure 8
【課題】実測値の測定精度を考慮して受信強度を精度よく算出する技術を提供する。【解決手段】受信強度算出装置において、実測値取得部62は、発信地点から送信された電波を複数の実測地点のそれぞれにおいて受信した場合の受信強度の実測値を取得する。理論値取得部60は、実測値取得部において取得される複数の受信強度の実測値のそれぞれに対応した受信地点での受信強度の理論値を取得する。導出部38は、複数の受信強度の実測値と、複数の受信強度の理論値とをもとに、受信強度との実測値と受信強度の理論値との差異を実測地点ごとに導出する。対象地点理論値取得部64は、受信強度算出の対象となる受信地点における受信強度の理論値を取得する。補正部36は、対象地点理論値取得部において取得した受信強度の理論値に対して、実測地点ごとの差異をもとにした補正を実行する。【選択図】図8 |
