Depth resolving power in near zone: Numerical results for a strip source

The problem of determining an unknown rectilinear source from the knowledge of its radiated field over a rectilinear bounded observation domain located in the near zone, orthogonal and centered with respect to the source is dealt with. In particular, we firstly analyze the information content of data by means of the Singular Value Decomposition of the radiation operator. Secondly, the resolution limits achievable in the reconstruction are discussed by examining the effect of the key geometrical parameters of the measurement configuration.
