[DOI: 10.21982/M8W888 ] Multiple Layers Single Reflections
Cardellach, Estel; Fabra, Fran
Multiple Layers Single Reflections (MLSR) is a model for L-band circularly polarized signals (such as GNSS signals) scattered off layered media. It assumes that the reflection off each layer is coherent, and that the signal splits into multiple path trajectories, each path suffering one single reflection solely. The model first computes the delay and amplitude of each reflected multi-path, taking into account the refraction and reflection angles, reflectivities and transmittivities at each interface, and attenuation along each layer. Then it sums coherently all these contributions with their corresponding amplitudes, shifting in delay and phase-delay. INPUT: layers' permittivities or parameterization (density, temperature, salinity...).
