Abstract

The simultaneous requirement for long wavelength and high spatial resolution for important geophysical remote sensing application, such as soil moisture and salinity, suggest the use of large to moderate sized deployable reflectors as a possible solution. Many studies have recognized the potential advantages of mesh reflectors. However, the emissivity of the reflector and its stability are major concerns and must the carefully considered to enable the advantages of deployable reflector technology for remote sensing applications. This paper will describe an advanced measurement system to evaluate the emissivity of reflector materials for these applications
