  • Demonstrator of Full Polarization Interferometric Radiometer (FPIR) is a one dimensional microwave interferometric radiometer with high resolution, light weight and low power consumption at X-band. The theory of polarimetry is analyzed to deduce the polarimetric visibility function in FPIR. To obtain the full polarimetric information, two kinds of different antenna arrays are designed in the FPIR system. Corresponding optimal polarization switching sequence for each sparse antenna array is also designed. The minimum degradation in sensitivity is achieved and sensitivities of the horizontal, vertical, and complex cross brightness temperatures are the same in the polarimetric mode of FPIR with the polarization switching sequence.
