ANALYSYS OF RADIO WAVE PROPAGATION CHARACTERISTICS FOR POSITIONING METHOD OF PEDESTRIAN IN BLIND AREA

摘要

The objective of this analysis is to devise a new positioning method of the pedestrian in ablind area, using the radio waves propagated from a transmitter carried by him. In order toanalyze propagation characteristics of radio waves arriving from the blind area, we haveconducted simple experiments and calculated it by the ray-trace method. The analysis showsthat the diffracted waves are dominant paths for the horizontal polarization, whereas thereflected waves are dominant paths for the vertical polarization. The results indicate that weshould focus on the polarization characteristics in our study that analyzes arrival radio wavespropagated from the blind area.
