Abstract
A polarimetric radar consisting of a transmission arrangement, in which the carrier signals have a circular polarization, wherein all the transmitters of the transmission arrangement are used simultaneously and each transmitter is operated by way of a transmission signal, which is modulated by way of an individual digital phase code, a receiver arrangement, which receives the reflected signals via an antenna arrangement, wherein there are both reception antennas that are configured for left-hand circularly polarized electromagnetic waves and reception antennas that are configured for right-hand circularly polarized electromagnetic waves, wherein the use of a plurality of transmitters and receivers provides an overall arrangement, which is operated in accordance with the multiple-input multiple-output method.
