Demonstrator of the Full Polarization Interferometric Radiometer (FPIR) is a light weight high resolution imaging polarimeter at X-band. It is based on techniques of one dimensional aperture synthesis. Differing from ESTAR-like precedents on polarimetric mode, conical antenna beam and 2-point calibration, FPIR employs two interlaced arrays. They are orthogonally polarized, therefore enable polarimetric...
A project to design and construct an airborne 8 mm band 2-Dimensional (2D) aperture synthesis radiometer BHU-2D was launched in the Electromagnetics Laboratory of BeiHang University (BHU). BHU-2D consists of 48 antenna/receiver elements, an FPGA-based 1 bit/2 levels digital cross-correlation subsystem, and a calibration subsystem. A ground based laboratory prototype of BHU-2D has been completed, which...
