Radio propagation estimating method and radio propagation estimating apparatus

摘要

A radio propagation path from a transmitting point to a receiving point is estimated accurately with a relatively small amount of calculation. A predetermined-size receiving area including the receiving point is set, radio propagation paths from the transmitting point to the receiving area is estimated by a ray launching method, object surfaces existing in the paths are extracted, and a radio propagation path from the transmitting point to the receiving point is estimated by an imaging method using only the extracted object surfaces.
