Inverse Source and Scattering Solution with Phaseless Data: Near Field In-Silico Validation

Abstract

The solution of an inverse source problem usually embraces the microwave imaging context. Indeed, microwave imaging solutions require the incident field distribution within the imaging domain. In the field of microwave imaging with amplitude only data, a phaseless inverse source problem has been addressed, by combining a holography-based method, directly operating into the spatial domain, with a source reconstruction method. The combined method is tested for the field characterization of a series of source with different directivity levels. Then the field modeling strategy has been included within a phaseless inverse scattering solution and applied to a 3D in-silico test case.
