Declarations under Rule 4.17: — of inventorship (Rule 4.17(iv)) Published: with international search report (Art. 21(3)) (54) Title: POLARIMETRIC PHASED ARRAY RADAR SYSTEM AND METHOD FOR OPERATING THEREOF -12 Fig. 2 (57) : A polarimetric phase array radar system (PPARS) for determination of parameters of a target and a method of operat- ing the PPARS are described. The PPARS includes an array having transceiver elements configured to transmit transmitting signal components of a dual-polarization signal having either a single type polarization or simultaneously two types of polarization. The ar- ray also configured to receive a receiving signal component having a single type of polarization. In transmitting mode, the transceiv- er elements are operative to transmit a signal component having one or two types of polarization. In receiving mode, the transceiver elements are divided into at least two sub-arrays. Each sub-array includes a first portion of the transceiver elements and a second portion of the transceiver elements, and is operative to receive a signal component having a first type polarization by the first portion of the transceiver elements and a signal component having a second type polarization by the second portion of the transceiver de - ments. 11111111111111011101111111111101011111011101011111011101110111011111111111110111111
