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

Abstract

In this paper a C-band (~5.6GHz), double channel, polarimetric, combined short-pulse scatterometer-radiometer system is described. The system was developed for short distance remote sensing application (from 6m up to 100m), from stationary fixed platforms or vessels. The minimum operational range for the scatterometer is 6m. This capacity allows study correlative features between microwave reflective and emission characteristics of the observed surfaces and medium under control-test laboratory conditions. Although the system was developed for polarimetric (vv, vh, hh, hv), simultaneous and spatially coincident microwave active-passive measurements of water surface, bare and vegetated soils and land snow cover parameters, it may be successfully used for atmospheric boundary layer remote survey too.

Multi-frequency and multi-polarization measurements of water surface radar cross section and brightness temperature angular dependences

“…A drive mechanism of the buggy allows stop it at any point of the path along the platform and perform measurements under any angle of incidence from the interval 0-80 0 . Detail descriptions of utilized CSRS are presented in [8,9,12,13]. The principal advantages of these unique devices and the whole measuring complex are the capability to perform, multi-frequency, spatio-temporally combined angular and polarization measurements of water surface microwave, active-passive characteristics, under far field conditions of sensing.…”

“…Spatio-temporally combined, multi-frequency, polarimetric, active-passive measurements is a sample of such synergy [4,5]. At present, there are several combined scatterometer-radiometer systems operating in various frequency bands [4][5][6][7][8][9][10][11]. Some of them are acceptable for very short distance remote sensing application [6][7][8][9][10][11], and allow carry out measurements under testcontrol, quasi-field conditions.…”

Therefore, a reason for a performance of spatio-temporally collocated, multi-frequency and multi-polarization, microwave active-passive measurements under test-control, quasi field conditions is appeared.…”
