介绍了被动微波遥感的两个新的技术-综合孔径微波辐射计和全极化参量微波辐射计.综合孔径微波辐射计采用干涉测量技术,用小天线的干涉基线组合合成大孔径天线的思想,提高被动微波遥感的空间分辨率,并实现视场范围的数字成像;全极化参量微波辐射计是一种新的微波遥感参数的探测技术,它测量目标微波辐射的全部4个Stokes极化参量,对于表面粗糙度各向异性特性的探测和目标的分类与识别具有很好的前景.

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.
