Engineering Contradiction Analysis
1Ease of operation
If a diffraction loss calculation formula is used to estimate diffraction loss, then the calculation process is simplified, but the accuracy of the diffraction loss analysis deteriorates
Solution Approach 1:
The patent introduces a correction coefficient as an intermediary element between the simple calculation formula and the actual diffraction loss. This correction coefficient, derived from terrain cross-sectional roundness characteristics, mediates the relationship by adjusting the formula's output to match measured values more closely, thus maintaining calculation simplicity while improving accuracy
Solution Approach 2:
The patent changes the parameter used in the calculation from generic terrain data to a specific parameter representing cross-sectional roundness. By calculating the roundness coefficient from terrain profile data and applying it as a correction factor, the system transforms a simple calculation into a more accurate one without fundamentally changing the calculation approach
2Reliability
If terrain data is used to calculate diffraction loss, then the analysis covers real-world conditions, but the complexity of the analysis increases
Solution Approach 1:
The patent extracts the essential characteristic of terrain (cross-sectional roundness) from the complete terrain data set. By identifying and isolating the roundness coefficient as the critical parameter affecting diffraction loss, the system reduces the complexity of processing complete terrain data while maintaining reliability in representing real-world conditions

AI summary
The diffraction loss analysis device calculates, 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. The diffraction loss analysis device generates 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.
