Consider two electric current sources radiating in free-space. They are assumed to be supported over two parallel strips whose positions are a priori known. Their radiated fields are collected over a single domain located in far-zone (with respect the whole radiating system). A two-dimensional scalar framework is set. The problem of separating the contributions of the two sources from their radiated field over a single domain is considered. A procedure based on two step is presented: in the first step the sources are reconstructed and in the second the field is computed by this currents. In order to reconstruct the sources, three different schemes of inversion are presented. Numerical examples are provided in order to compare the different strategies from the achievable performance and numerical complexity point of views.
