Title:
アンテナ装置、レーダシステム、及びアンテナ回転方法
Document Type and Number:
Japanese Patent JP6674534
Kind Code:
B2
Abstract:
The purpose is to reduce interference of a radio wave transmitted from an antenna with other radio waves. An antenna device 8a is provided, which may include a rotatable antenna 10, a time information acquirer 24, an antenna rotation start reference time setter 32, a periodic signal acquirer 22, and a rotation control processor 33a. The time information acquirer 24 may acquire time information. The antenna rotation start reference time setter 32 may set an antenna rotation start reference time based on the time information. The periodic signal acquirer 22 may acquire a periodic signal repeated at a constant cycle larger than a time error of the time information. The rotation control processor 33a may determine a rotation start timing at which the antenna starts rotating, based on the antenna rotation start reference time and the periodic signal.
