Abstract

Weather radar system which uses antennas constituted by the elongated aperture of waveguides, and form at least an array (510, 520) mounted on a rotating horizontal (502), and the said apertures are as wide as one wavelength (λ) and length higher than 20λ, wherein the small aperture in azimuth ranges from 0.5° to 2° and is synthesized by high rotational speeds together with signal processing techniques such as ROSAR.

Claims

8-1. Weather radar system, in conformity with claim 1, characterized in that the emitted electromagnetic waves are polarized both horizontally and vertically and allow, after processing of the received signal, the characterization of the particles which reflected the signal.
