Preliminary results of multi-frequency (at C, Ku and Ka-band of frequencies), polarimetric measurements of snow, bare and vegetated soil reflective and emissive characteristics angular dependences

摘要

In this paper a measuring complex of C-, Ku and Ka-band, multi-polarization, combined scatterometer-radiometer systems, their structures and operational features, measuring platforms and calibration facilities are presented. As well as the results of preliminary, spatio-temporally collocated, multi-frequency and multi-polarization measurements of bare soil microwave reflective (radar backscattering coefficient) and emissive (brightness temperature) characteristics angular dependences at 5,6GHz and 15GHz are presented, under various soil moisture and air temperature conditions.
