Abstract :
A hybrid approach to microwave imaging has been presented by combining the computational effectiveness of the nLSM with the global optimization capabilities of ACO. The reported numerical results validate the ability of the method to satisfactorily solve diagnostic problems by exploiting strengths of the two ones.
