Title:
RADIO WAVE ARRIVAL ANGLE DETECTION DEVICE, VEHICLE DETECTION SYSTEM, RADIO WAVE ARRIVAL ANGLE DETECTION METHOD, AND VEHICLE ERRONEOUS DETECTION PREVENTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/157613
Kind Code:
A1
Abstract:
A radio wave arrival angle detection device of the present invention extracts symbols and resolves the same into sub-carriers having various frequency components, for OFDM carrier waves received by a first antenna and a second antenna, respectively. The arrival angle of the carrier waves is calculated on the basis of the geometric relationship between the phase shift of the respective sub-carriers of the OFDM carrier waves received by the first antenna and the second antenna and the arrangement of the first antenna and the second antenna.
