Problems solved by technology

The equivalence evaluation method based on the experience of the testers in a strong electromagnetic environment strongly relies on the prior knowledge of the testers, and the evaluation results are difficult to quantify; especially, when the environmental waveform is relatively complex, it is difficult to give a high-confidence evaluation result

Based on the extraction and measurement of characteristic parameters to construct an equivalence evaluation method in a strong electromagnetic environment, it is necessary to measure different signal characteristic parameters for comparison according to different signal styles. This method requires prior knowledge of the signal style; especially when performing When constructing equivalence evaluation in a complex strong electromagnetic environment, additional signal pattern recognition algorithms are required, which increases the difficulty of evaluation and the uncertainty of results, and greatly reduces the actual operability; in addition, due to the different types of signal parameters of different patterns, the evaluation results It is difficult to quantify uniformly, and to a certain extent, it is difficult to give high-confidence quantitative and grading evaluation results

[0004] In view of the lack of a convenient and highly reliable method for quantitatively evaluating the equivalence of building a strong electromagnetic environment, the present invention proposes a method for quantitatively grading and evaluating the equivalence of building a strong electromagnetic pulse environment
