The frequency range and distortion model affected by Faraday rotation were analyzed. A kind of calibration algorithm was introduced, in which trihedral corner reflectors were used to calibrate POLSAR image subject to channel imbalance, Faraday rotation and RCS distortion. [2]Three kinds of target decomposition theorems used to extract polarimetric features of SAR image were studied in detail. A kind of POLSAR MLC image data decomposition method based on classical coherent decomposition theorem of POLSAR SLC image was introduced, which was used to extract polarimetric features of POLSAR MLC image.

But using infrared CCD, which has little scattering light, strong penetration ability, can improve image quality greatly. This paper analyzes the effects on surveillance by Rayleigh scattering, Mie scattering and unselective scattering theoretically. In addition it discusses the relation between transmission coefficient, reflection coefficient and wavelength of infrared CCD.
