Abstract

　本発明により、推定時に考慮する全体エリアのうち、限定された評価エリアの電波伝搬特性を高速かつ高精度に推定することが可能な電波伝搬シミュレータが提供される。空間上に定義された複数のオブジェクトを用いて送信点から空間上のうちの限られた評価エリアに至る電波の伝搬状況を推定する電波伝搬シミュレータは、評価エリアに到達するパスを幾何光学的な伝搬推定手法を用いて抽出する抽出手段（パス抽出部２０）と、抽出手段で抽出されたパスと評価エリアの幾何学的な情報とを用いてオブジェクトを選択する選択手段（オブジェクト選択部３０）と、選択手段で選択されたオブジェクトのみを用いて送信点から評価エリア内部に至る詳細な電波伝搬状況を推定する推定手段（電波伝搬特性推定部４０）とを有する。
