1. A polarimetric radar comprising:
a plurality of transmitters forming a transmission arrangement, the transmission arrangement being configured so that carrier signals from the transmitters have a circular polarization, and during operation each transmitter is used simultaneously to provide a transmission signal that is modulated by an individual digital phase code; and
a plurality of reception antennas forming a receiver arrangement configured to receive, reflected signals, the reception antennas comprising reception antennas that are configured for left-hand circularly polarized electromagnetic waves and reception antennas configured for right-hand circularly polarized electromagnetic waves,
wherein the polarimetric radar is configured for multiple-input multiple-output operation.
