| Abstract |
SPIRA is a passive polarimetric imaging radiometer operating at 91 GHz (W-band). The overall objective is to obtain signatures of the brightness temperature distribution of the Earth's surface in all four Stokes parameters. Collectively, the four Stokes parameters provide a complete characterization of the Gaussian-random electromagnetic field (i.e., full scattering matrix), a prerequisite for the interpretation of microwave data. A radiometric sensitivity of < 1 K is achieved with a superheterodyne receiver at a bandwidth of 2 GHz, millisecond (ms) sampling time and post-measurement digital integration. The antenna has been designed with special attention paid to the minimization of measurement errors due to side lobes and cross-polarization. A scanning subsystem makes maps in azimuth and elevation, that are presented in the form of images.
