| Research Abstract |
To investigate the effect of snow on Localizer Antenna in snowy region airport , the field experiments using a scale model LPDA(Log Periodic Dipole Antenna) and analysis based on FDTD method were conducted. From the comparison between the results of experiment and analysis, the effectiveness of FDTD simulation of LPDA covered with snow was confirmed. New simulator for analyzing the course characteristic of localizer system considering snow and ground conditions (snow depth, snow dielectric properties, ground slope, runway slope etc.) was developed and confirmed to be available for evaluating a course variation case in Aomori Airport.
