Polarimetric, L-band, combined radiometer and short pulse scatterometer system

The results of spatio-temporally combined microwave active-passive measurements of bare and vegetated soil at 37 GHz

“…More detail description of SRS may be found in [22,23]. Before each series of measurements a calibration of the SRS was carried out by sky and by a layer of microwave absorber with a reflection coefficient better than -25dB at 37Ghz of frequencies (Photos 3 and 4).…”

C-band polarimetric combined short-pulse scatterometer/radiometer system for platform and vessel application

“…In comparison with earlier developed scatterometer-radiometer systems of S (~3GHz), K (~20GHz) and Ka (~37GHz) band of frequencies [10][11][12][13][14][15], the described system has two receiving channels, which allow simultaneously receipt both co-and cross polarized components of the backscattered signals and the signals of the observed surface proper radiothermal emissions, at vertical and horizontal polarizations. .…”

“…Such a task was solved in the framework of the ISTC (International Science and technology Center) Project A-872 with the main goals to develop and to build an experimental site equipped by a measuring complex of L-Ka band combined, short pulse scatterometer-radiometer systems for short distance application (at ~6m minimum operational range for scatterometers). The objectives of the above mentioned Project were successfully achieved and S (~3GHz), K (~20GHz) and Ka (~37GHz) band polarimetric, combined, short pulse scatterometer-radiometer systems were developed and tested in field conditions by ECOSERV Remote Observation Centre Co. Ltd. [10][11][12][13][14][15].…”

S-Band, Polarimetric, Combined, Short Range Action Scatterometer-Radiometer for Platform and Vessel Application

“…Such a system of Ka-band (37GHz) of frequency was recently developed, manufactured and tested in field conditions by ECOSERV Remote Observation Centre Co.Ltd [1,2]. The results of preliminary measurements of water surface, snow, soil and vegetation microwave reflective and emissive characteristics by above mentioned Ka-band, polarimetric, short pulse, combined scatterometer-radiometer system have indicated on a necessity to carry out multi frequency, combined active passive, polarimetric measurements to develop, to validate and to improve existed electromagnetic scattering and radiative transfer models for sea wave, soil, snow and vegetation.…”
