The inhomogeneous square example. (a) Real part of the contrast reference profile. (b) Normalized logarithmic LSM indicator with the selected pivot points superimposed as dots. The retrieved profile by means of the approach (4) ( and err = 10%): (c) real and (d) imaginary part. The retrieved profile by means of the approach (6) ( and err = 7%): (e) real and (f) imaginary part.
