Polarimetric imaging of land in airborne verification experiment for polarimetric scatterometer

Through the effective combination of polarization and interferometry information, PolInSAR can simultaneously measure the three-dimensional spatial structure and scattering properties of the illuminated target, it provides the possibility of extracting the high-precision digital elevation information and slight deformation information of observed object, so quantitative microwave remote sensing can be realized¹. The construction, data processing technique and applied research of PolInSAR system have been the research hotspot of SAR at home and abroad. In this paper, a Ku-band polarimetric interferometric radar system is constructed, and in the recent airborne flight experiments, preliminary images of observed area with obvious polarimetric characteristic are acquired, which lays the foundation for further extracting the polarization and interferometry information.
