ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/030160
Kind Code:
A1
Abstract:
Provided is an electronic device capable of specifying the direction of a direct wave with high accuracy. The electronic device (first electronic device (1)) comprises: a reception unit (12) which is equipped with an array antenna and receives a detection radio wave transmitted from another electronic device equipped with another array antenna; an estimation unit (16) which estimates the emission/arrival direction of the detection radio wave; and a specifying unit (17) which specifies the direction of the direct wave of the radio wave between the electronic device and the other electronic device, on the basis of the emission/arrival direction of the detection radio wave, wherein the detection radio wave has a beam pattern obtained by fixing the directivity of the array antenna and switching the directivity of another array antenna.
