Title:
RADAR
Document Type and Number:
WIPO Patent Application WO/2008/016033
Kind Code:
A1
Abstract:
A radar having high time/high space resolution in which volume scanning can be
performed with an inexpensive and simple arrangement, and the size and weight
can be reduced. The radar (50) is equipped with an antenna section (51) consisting
of a radio wave lens antenna unit having a spherical radio wave lens (2) for transmission,
a spherical radio wave lens (3) for reception, a primary radiator (4) arranged
at the focal point of the radio wave lens (2), and a primary radiator (5) arranged
at the focal point of the radio wave lens (3). The primary radiators (4, 5) rotate
in the direction of the angle of elevation with the axis connecting the centers
of the radio wave lenses (2, 3) as the axis of rotation, and rotate in the direction
of the azimuth angle with the axis perpendicular to the axis connecting the centers
of the radio wave lenses (2, 3) as the axis of rotation.
