MULTIPATH DETECTION METHOD AND ANGLE OF ARRIVAL CALCULATION DEVICE

摘要

A multipath detection method for accurately detecting a multipath is provided. This multipath detection method involves determining the presence or absence of a multipath from signals received by a plurality of antennas, and is characterized in that each signal received by each antenna is converted into a frequency domain, and the presence or absence of a multipath is determined by comparing the inter-antenna balance of the amplitude characteristics and/or the frequency characteristics of the frequency domains. This configuration enables a multipath to be accurately detected by converting each received signal into a frequency domain and comparing the inter-antenna balance of the amplitude characteristics and/or phase characteristics of the frequency domains.
