Embodiment Construction

[0078] In order to illustrate how to evaluate the effectiveness of reconstructing the electromagnetic environment, how to reconstruct the electromagnetic environment is explained here first. figure 1 Shown is a schematic diagram of the electromagnetic environment reconstruction. The present invention evaluates the electromagnetic environment reconstructed based on the field strength distribution at a specific frequency point. In the signal source placement area where the electromagnetic environment is reconstructed, the signal source is placed in a certain way to reconstruct the actual electromagnetic environment.

[0079] The relevant instructions are as follows:

[0080] Actual electromagnetic environment: A real electromagnetic environment.

[0081] Actual Evaluation Area: The area in the actual area used to evaluate the similarity.

[0082] Reconfiguration of the EM Environment: Another area dedicated to reconfiguration of the EM environment.

[0083] Reconstruction Ev...

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.

Description

technical field [0001] The invention belongs to the field of electromagnetic environment reconstruction, in particular to an electromagnetic environment similarity assessment method based on field intensity distribution, which is used for evaluating the effectiveness of reconstructing the electromagnetic environment. Background technique [0002] With the development of science and technology, the number of communication stations is increasing, the signal density is increasing, the frequency band is continuously expanding to the high and low ends, new communication systems are emerging, and the transmission methods are diversified. This will inevitably form a complex and dense electromagnetic environment for communication signals.
