Abstract
Conventional equivalent source reconstruction methods (SRM) require both phase and amplitude information of the acquired fleld data. However, there are situations where the phase information is not available or impractical to obtain. Hence, the development of SRM using phaseless flelds is important. In this paper, a novel iterative SRM based on phaseless electric flelds is presented. The reconstructed equivalent current source can be electric, magnetic current, or both. They can flt the physical geometry of the radiator. Electric fleld integral equation (EFIE) is employed to build the relationship between the reconstructed current source and measured flelds. It can precisely reproduce the original 3D radiation pattern with very good accuracy. To investigate the robustness and accuracy of the proposed approach, both strong and weakly-directional radiators are benchmarked.
