Abstract: A polarimetric phase array radar system (PPARS) for determination of parameters of a target and a method of operating 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 array also configured to receive a receiving signal component having a single type of polarization. In transmitting mode, the transceiver 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 elements.
