Abstract :
This paper first presents the concept of the full polarization interferometric radiometer (FPIR). FPIR is to implement high resolution polarimetric radiometry without system complexity. The basic composition of FPIR is introduced. An example or schematic of all four elements of the FPIR is demonstrated, especially focusing on the design of the digital correlator. In the end, the image of FPIR is presented.
