In this contribution a new method for inverse obstacle scattering problem is proposed starting from a recently introduced smart rewriting of the scattering equations, known as New Integral Equation (NIE) model. This latter involves a redefinition of the contrast function encoding the target properties. Interestingly, in both cases of strong and metallic scatterers, this function turns to be approximatively real, homogenous and approaching the unitary value. These properties are then exploited in the proposed method to accurately retrieve the shape and size of strong and/or metallic targets, as described in the following.
