Supporting of cylindrical polarimetrie phased array radar development using configurable phased array demonstrators (CPAD)

Configurable Phased Array Demonstrator (CPAD) was developed since 2010 for the scalable verification and risk mitigation of the Multi-Function Phased Array Radar (MPAR) at sub-array level. This work reviews the basic concepts and solutions of CPAD and focuses on the development of a single linear column array and multiple planned experiments of CPAD, to support the development of future Cylindrical Polarimetric Phased Array Radar (CPPAR). The paper describes several new developments related to CPAD: (1) Dual-polarized linear array as a "column" of a new CPPAR, (2) Scalable validation through laboratory measurements at different frequencies, (3) Virtual array through rotating platform, (4) Passive sensing with coordination of remote transmitters.
