Computational electromagnetism methods underlie modern methods for determining antenna radiation patterns based on electromagnetic field measurements, in particular, the method of source reconstruction. Although it is widely recognized that these methods solve physically correct equations and give physically reliable results, verifying the reliability of the source reconstruction method, i.e. verification, as well as evaluating its accuracy, remains an important and ongoing problem, especially when implemented in the real manufacturing sector. Therefore, the article considers the issue of verifying and evaluating the accuracy of the source recovery method for estimating the antenna pattern based on the results of measurements in the near field. The article describes the mathematical theory of the source recovery method. Various options for implementing the method are being considered. Based on analytical solutions to the problem of scattering spherical objects, the method has been proposed for verifying the results of determining the antenna pattern from measurements of the electromagnetic field in the near zone. Within the framework of the proposed methodology, verification has been carried out, the accuracy of the source reconstruction method for various source data has been determined, and the new functionality of this method has been clearly demonstrated.
