MULTIPATH DETECTION METHOD, MULTIPATH DETECTION DEVICE AND ANGLE OF ARRIVAL CALCULATION DEVICE

摘要

A multipath detection method for accurately detecting a multipath is provided. This multipath detection method involves detecting a multipath in multipath detection intervals on the basis of a delay profile of a transmission path calculated from a signal received by an antenna, and is characterized in that, when A/B, where A represents the signal power of a first interval centered by the peak of a main wave that arrives earliest in each multipath detection interval, and B represents the signal power of a second interval that excludes the first interval in the relevant multipath detection interval, is less than a first threshold value, a multipath is assessed as existing, and if A/B is larger than the first threshold value, a multipath is assessed as not existing.
