Document Type and Number:
WIPO Patent Application WO/2017/169300
Kind Code:
A1
Abstract:
[Problem] TO reduce interference between radio waves transmitted from an antenna and other radio waves. [Solution] An antenna device (8) is provided with a rotating antenna (10), a time instant information acquiring unit (24) for acquiring time instant information, an antenna rotation initiation reference time instant setting unit (32) for setting a reference time instant for initiation of antenna rotation on the basis of the time instant information, a periodic signal acquiring unit (22) for acquiring a periodic signal repeated at a certain period greater than a time error of the time instant information, and a rotation control processing unit (33) for determining a rotation initiation timing at which rotation of the antenna is initiated on the basis of the antenna rotation initiation reference time instant and the periodic signal.
