Abstract :
A hybrid approach for phaseless microwave imaging is proposed in this work. A two-probes near-field measurement strategy with the related phase-retrieval method is adopted to obtain the input data for a microwave imaging procedure based on an inexact-Newton method. The approach performances are firstly assessed by numerical simulations. Moreover, preliminary experimental validations are provided to show the effectiveness of the proposed method.
