Diffraction loss analysis device, diffraction loss analysis method, and recording medium

A diffraction loss analysis method comprising:

• calculating, using a diffraction loss calculation formula, an estimated value of the diffraction loss of a radio communication path on the basis of terrain data indicating the ground surface corresponding to the radio communication path between the installation location of a transmission-side antenna and the installation location of a reception-side antenna, and
• generating a roundness loss estimation model that estimates roundness loss in accordance with the cross-sectional roundness in the direction of the radio communication path on the ground surface indicated by the terrain data, on the basis of the relationship between the estimated value of the diffraction loss and the diffraction loss calculation formula, and the actual measured value of the diffraction loss.

A non-transitory recording medium that stores a program for causing a computer of a diffraction loss analysis device to execute:

• calculating, using a diffraction loss calculation formula, an estimated value of the diffraction loss of a radio communication path on the basis of terrain data indicating the ground surface corresponding to the radio communication path between the installation location of a transmission-side antenna and the installation location of a reception-side antenna, and
• generating a roundness loss estimation model that estimates roundness loss in accordance with the cross-sectional roundness in the direction of the radio communication path on the ground surface indicated by the terrain data, on the basis of the relationship between the estimated value of the diffraction loss and the diffraction loss calculation formula, and the actual measured value of the diffraction loss.
