An Evaluation Method of Electromagnetic Environment Similarity Based on Field Strength Distribution

Abstract

The invention belongs to the field of electromagnetic environment reconstruction and particularly discloses an electromagnetic environment similarity evaluation method based on field intensity distribution. The method is characterized by at least comprising the following steps of step 1.respectively carrying out meshing on an actual evaluation area and a reconstructed evaluation area to obtain field intensity amplitudes of the actual evaluation area and the reconstructed evaluation area; step 2.giving four indexes, namely mean contrast, standard deviation contrast, a correlation coefficient and relative degree, and corresponding criterions corresponding to the indexes based on mathematical statistics and a set pair analysis theory; step 3.respectively establishing conversion functions according to the attributes of the four indexes in the step 2; and step 4.establishing a comprehensive evaluation function according to a result of the step 3, and carrying out normalization processing onthe comprehensive evaluation function to obtain an electromagnetic environment similarity evaluation function; and lastly, giving a criterion corresponding to the function. The method is used for evaluating the effectiveness of the reconstructed electromagnetic environment.
