Popis: For large, complex systems with multiple sources at the same frequency, localizing the sources of radiation often proves difficult. This paper presents an emission source microscopy (ESM) technique derived from synthetic aperture radar (SAR) to localize radiating sources on a PCB. Near-field scanning provides limited information about the components contributing to far-field radiation. This paper presents the source localization methodology, supported by simulation and measurement results. After localizing the sources, the far-field contribution and the total radiated power from each individual source can be estimated. The results show that the proposed method can distinguish between multiple radiating sources on a complex PCB.
