Abstract:
A wind speed radar (1) comprises a spherical transmitting/receiving lens antenna
(2) so formed of a dielectric that the dielectric constant varies at a predetermined
rate in the radial direction and transmitting/receiving primary radiators
(3Z, 3N, 3S, 3E, 3W) disposed along the outer periphery of the lens antenna (2)
at the focuses of the radio waves transmitted/received through the lens antenna
(2) in the direction of azimuths to be observed. The lens antenna (2) is supported
