Abstract
According to one embodiment, an antenna device comprises an antenna panel including a first transmission antenna, a first reception antenna, and a second reception antenna, and a rotation device configured to rotate the antenna panel. A first radio wave is irradiated from the first transmission antenna when a rotation angle of the antenna panel is a first angle and a reflected radio wave of the first radio wave is received by the first reception antenna and the second reception antenna. A second radio wave is irradiated from the first transmission antenna when the rotation angle is a second angle and a reflected radio wave of the second radio wave is received by the first reception antenna and the second reception antenna.
Claims15
An antenna device comprising:
- an antenna panel including a first transmission antenna, a first reception antenna, and a second reception antenna;
- and
- a rotation device configured to rotate the antenna panel around a point on the antenna panel as a rotation center, wherein
- a first radio wave is irradiated from the first transmission antenna when a rotation angle of the antenna panel is a first angle and a reflected radio wave of the first radio wave is received by the first reception antenna and the second reception antenna;
- and
- a second radio wave is irradiated from the first transmission antenna when a rotation angle of the antenna panel is a second angle different from the first angle and a reflected radio wave of the second radio wave is received by the first reception antenna and the second reception antenna.
A system comprising:
- a reception device configured to
- receive information on a reflected radio wave of a first radio wave when a rotation angle of an antenna panel including a transmission antenna and a first reception antenna and a second reception antenna is a first angle, the first radio wave being irradiated from the transmission antenna, reflected by an object, and received by the first reception antenna and the second reception antenna, and
- receive information on a reflected radio wave of a second radio wave, when a rotation angle of the antenna panel is a second angle, the second radio wave being irradiated from the transmission antenna, reflected by an object, and received by the first reception antenna and the second reception antenna;
- and
- an output device configured to output information about the object.
A transmission/reception method comprising:
- receiving information on a reflected radio wave of a first radio wave when a rotation angle of an antenna panel including a transmission antenna and a first reception antenna and a second reception antenna is a first angle, the first radio wave being irradiated from the transmission antenna, reflected by an object, and received by the first reception antenna and the second reception antenna;
- receiving information on a reflected radio wave of a second radio wave, when a rotation angle of the antenna panel is a second angle, the second radio wave being irradiated from the transmission antenna, reflected by an object, and received by the first reception antenna and the second reception antenna;
- and
- outputting information about the object.
