<P>PROBLEM TO BE SOLVED: To provide technique for improving estimation accuracy of a pre-interference amount while an increase of a calculation amount is suppressed. <P>SOLUTION: A neighbor electric field calculation section 112 assumes an area surrounding a transmission point where a transmitter is arranged and derives a position and a direction, to which a radio wave transmitted from the transmitter goes out from the area, by a first calculation method. A remote electric field calculation section 114 derives electric field strength when the radio wave is transmitted in a direction which the neighbor electric field calculation section 112 derives from the position which the neighbor electric field calculation section 112 derives by a second calculation method. A result display section 116 notifies of the electric field strength as the pre-interference amount. The first calculation method in the neighbor electric field calculation section 112 minutely reflects influence of reflection of the radio wave by an obstacle more than the second calculation section in the remote electric field calculation section 114. <P>COPYRIGHT: (C)2013,JPO&INPIT |
