For electric waves emitted from a base station, an arrival area of reflection waves thereof is determined according to a reflection object by which the electric waves are last reflected and a fictitious transmitting point decided for the reflection object. Received power of reflection waves is calculated for each evaluation point in the particular area. Since the calculation is conducted for the limited area, the period of time required for the calculation is remarkably minimized while retaining the precision of calculation when compared with the case in which the calculation is achieved for all related areas. |
