On-Site Radiated Emissions Result Visualization Using Augmented Reality

Abstract

By focusing on regions exhibiting maximum electromagnetic (EM) emission levels, the duration required for standard EM emissions measurements can be substantially reduced. This letter outlines a rapid prescan technique that adheres to conventional measurement procedures. The proposed method considerably minimizes measurement time by identifying areas where emissions approach, or exceed, threshold limits. Furthermore, real-time visualization of EM emissions from the time-domain data enables testers to select a more effective scanning trajectory, thus diminishing the likelihood of overlooking areas with high-intensity EM emissions and time-variance sources.
