Multi-frequency and polarimetric measurements of bare and vegetated soils microwave reflection and emission by C- and Ku-band, combined scatterometer-radiometer systems

In this paper the results of simultaneous and spatially coincident, multi-frequency, polarimetric, spatio-temporally collocated measurements of bare, dry vegetated and ash covered soils microwave reflective (radar backscattering coefficient) and emissive (brightness temperature) characteristics angular dependences at ~5.6GHz and ~15GHz are presented. During these experiments the observed area was set ablaze and multi-frequency, multi-polarization, microwave active and passive measurements at 30⁰ incidence angle were continued for smock, fire and ash situations. For these measurements C-, and Ku-band, polarimetric, combined scatterometric-radiometric systems were used, set jointly on a mobile buggy moving along the measuring platform. Structures, operational features and the main technical characteristics of the utilized systems are presented too. The paper has an aim as well to attract attention of interested researchers and to invite them to perform their own or joint researches using available devices and facilities.
