AbstractIn the past three decades, GNSS-R/IR has emerged as a new and promising remote sensing technique. Its applications have extended from ocean surface to land scenario. However, to our knowledge, few works focus on the soil salinity detection by GNSS-R/IR. For the first time, this paper studies the feasibility of soil salinity detection by using the microwave scattering models. As the reflected signals or interferometric signals of the GNSS constellations are collected from the first Fresnel zone, Fresnel reflectivities at both linear and circular polarizations are used to simulate the coherent scattering of soil salinity. In order to consider the azimuth angle effects, i.e. to consider the scattering coming from the specular cone, the advance integral equation model is employed. Our scattering simulations at both linear and circular polarizations indicate that soil salinity is detectable at some angles. The polarizations and angles should be carefully considered to find the best combinations for detection.
