First Claim
Patent Images
1. A polarimetric radar, comprising:
- a transmission assembly comprising transmission antennas that emits circularly polarized waves during operation of the polarimetric radar; and
a receiver assembly that receives reflected components of the circularly polarized wave using an antenna assembly during operation of the polarimetric radar,wherein the receiver assembly comprises a plurality of two-channel receivers which, during operation, simultaneously receive clockwise- and anticlockwise-rotating circularly polarized signal components with a common phase center which are provided for digital beam shaping downstream of the antenna assembly.

Abstract
The present invention relates to a polarimetric radar, consisting of a transmission assembly that emits circularly polarized waves by means of transmission antennas and a receiver assembly that receives the reflected circularly polarized wave components by means of an antenna assembly. A plurality of two-channel receivers are provided as the receiver assembly, which simultaneously receive clockwise-rotating and anti-clockwise-rotating circularly polarized signal components, which are provided for digital beam shaping downstream of the antenna assembly. The invention further relates to a method for object classification.
