Title:
RADIO WAVE DIRECTION-OF-ARRIVAL ESTIMATION DEVICE AND RADIO WAVE DIRECTION-OF-ARRIVAL ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162104
Kind Code:
A1
Abstract:
A radio wave direction-of-arrival estimation device according to one embodiment is characterized by having: a radio wave absorbent body which extends in the vertical direction; a plurality of non-directional antennas which are positioned around the radio wave absorbent body so as to extend in the same direction as does the radio wave absorbent body; a measurement unit for measuring the C/N value or the received power of each radio wave received by the plurality of non-directional antennas; an estimation unit for estimating the direction of arrival of the radio waves on the basis of each C/N value or received power measured by the measurement unit; and an output unit for outputting information which expresses the direction of arrival of the radio waves which was estimated by the estimation unit.
