Radio wave propagation characteristic estimation system, radio wave propagation characteristic estimation method, radio wave propagation characteristic estimation program

摘要

Disclosed are a radio wave propagation characteristic estimation system, radio wave propagation characteristic estimation method, and radio wave propagation characteristic estimation program for estimating propagation characteristics of radio waves at high speeds, without deteriorating accuracy. An object selection module reads map data prerecorded on a map data memory unit and selects structures from the structures indicated in structure data included in the map data according to the height thereof, a radio wave propagation path calculation module searches for the path of radio waves emitted from a transmission point based on the structure data related to the selected structures and location data for the transmission point and an observation point, and calculates the propagation path of the radio waves until the radio waves reach the observation point, and a radio wave propagation characteristic estimation module estimates the propagation characteristics of radio waves at the observation point based on this calculated path.
