New Developments of the Passive Microwave Remote Sensing Technologies--Synthetic Aperture Microwave Radiometer and Full Polarized Parameter Microwave Radiometer

In this summarized paper, two new developments of the passive microwave remote sensing-the interferometric synthetic aperture microwave radiometer and the full polarized parameter microwave radiomter are introduced. By interferometric measurement of small aperture antennas with different baselines, large dimension receiving aperture is synthesized to improve the spatial processing. The full polarized microwave radiometer measures all the four parameters of the Stokes vector of the electromagnetic emission from observed targets. More and more potential applications of the full polarization parameters are exploiting for the measurement of surface anisotropy, classification and identification of targets.
