| Outline of Final Research Achievements |
By experiments using the localizer (LOC) scale model antenna, event problems due to snow cover that had been identified in the operation site has been reproduced. In addition, from the verification of the analytical results using the physical optics method and the experimental results , it was to clarify the relationship of the LOC front of the snow situation and the directional system and a side band system radiation field characteristic variation. Moreover, the possibility to suppress the variation of the DDM value by snow surface reflected wave with the reflected wave shielding fences, was verified from the electromagnetic field analysis.
