Attenuation data from microwave communication links can be used to retrieve rainfall fields, for instance by applying tomographic inversion algorithms. If links operate at different frequencies, they experience different attenuation levels for the same rain intensity. As the relation between specific attenuation and frequency is non-linear, this complicates the tomographic inversion algorithm with respect to single-frequency networks. In this contribution, we propose an innovative tomographic reconstruction algorithm that permits to deal with heterogeneous frequency links and we assess it through simulations.

Abstract

Attenuation data from microwave communication links can be used to retrieve rainfall fields, for instance by applying tomographic inversion algorithms. If links operate at different frequencies, they experience different attenuation levels for the same rain intensity. As the relation between specific attenuation and frequency is non-linear, this complicates the tomographic inversion algorithm with respect to single-frequency networks. In this contribution, we propose an innovative tomographic reconstruction algorithm that permits to deal with heterogeneous frequency links and we assess it through simulations.
