RADIO WAVE ENVIRONMENT ESTIMATION METHOD AND RADIO WAVE ENVIRONMENT ESTIMATION DEVICE

WIPO Patent Application WO/2019/159965

A1

According to the present invention, the intensity of a radio wave is estimated by: calculating, for each piece of reception antenna coordinate information, a synthesized reception intensity value when indirect waves of the radio wave, which have been generated by an obstacle, are synthesized in consideration of the phases of the indirect waves; taking, as input information, the synthesized reception intensity value for each piece of reception antenna coordinate information that corresponds to transmission antenna coordinate information; taking, as teacher information, information that indicates a reception state of the radio wave obtained in a location of a reception antenna by actual measurement or a method other than the actual measurement for the radio wave output from a corresponding transmission antenna; generating relevance information which indicates the relevance between the input information and the teacher information; and calculating information for indicating a reception state of the radio wave on the basis of transmission antenna coordinate information for evaluation and the generated relevance information.
