Abstract
In this paper a Ku-band (15GHz), dual polarization, combined short-pulse scatterometer-radiometer is developed for short distance remote sensing of the water surface, bare soil and snow cover, as well as for simultaneous and coincident measurements of the microwave reflective and emissive characteristics of the observed medium under laboratorycontrolled conditions. The system allows us carry out polarimetric (vv, vh, hh, hv), simultaneous and coincident microwave active-passive measurements of the observed surface (soil, vegetation, snow and water surface) parameters at angles of incidence from 0-60°. The originality of the developed system is in the spatial-temporal combination of microwave active and passive channels of observation and its application for short distance sensing (the minimum operational range for the scatterometer is ~6m) from low altitude platforms under far field conditions for both radar and radiometric observations.
