摘要： A radar having a high time and high spatial resolution and being capable of performing volume scanning with an inexpensive and simple structure, while enabling reduction is size and weight. A radar (50) is provided with an antenna unit (51) including a radio wave lens antenna device, which has a spherical transmission radio wave lens (2), a spherical reception radio wave lens (3), a primary radiator (4) arranged at a focal point of the radio wave lens (2), and a primary radiator (5) arranged at a focal point of the radio wave lens (3). The primary radiators (4, 5) pivot in an elevation direction about an axis connecting center points of the radio wave lenses (2, 3) and pivot in an azimuthal direction about an axis orthogonal to the axis connecting the center points of the radio wave lenses (2, 3).

摘要： An electromagnetic lens device includes an electromagnetic lens (2) for transmission, an electromagnetic lens (3) for reception, two primary radiators (4,5) each located at a focal point of one of the electromagnetic lenses (2,3), an arm (12) holding the primary radiators (4,5), and a table (8). The arm (12) is rotatable about a first axis (A) that extends through the centers of the electromagnetic lenses (2,3). The table (8) is rotatable about a second axis (B) that is perpendicular to the first axis (A). The primary radiators (4,5) rotate about the first axis (A) together with the arm (12), and rotate about the second axis (B) together with the table (8).
