| Abstract: | In this paper a novel system of the X band
radiometer scatterometer developed by our Institutions is reported. By using this system,
multi polarized (VV,HH,VH,HV) backscattering coefficients for active remote sensing and V,H
polari zed brightness temperature for passive remote sensing can be measured simultan
eously. Some measurements of scattering and emission from tree canopy with and without
artificial metal targets are presented. Theoretical study of scattering and emission from a layer
of random medium is discussed with data analysis. Ou r approach provides an example of
correlated active passive remote sensing and application for target detection in environmental
clutters. |
