technical field [0001] The invention relates to the technical field of electromagnetic environment effects, in particular to a method for quantitatively evaluating the equivalence of complex electromagnetic environment construction. Background technique [0002] In recent years, the increasingly complex electromagnetic environment has posed a great threat to the viability of electronic systems. Electronic systems are susceptible to electromagnetic wave interference and have different degrees of electromagnetic environmental effects, such as: interference, disturbance, system performance degradation, damage or even damage, etc. , affecting its performance. In order to ensure that the electronic system can adapt to the external electromagnetic environment and work stably and reliably, it is necessary to carry out electromagnetic environment effect tests to study and verify the adaptability of the electronic system to complex electromagnetic environments. Before carrying out t...

Problems solved by technology

However, for the actual complex electromagnetic environment, in most cases, only discrete signal values ​​that change with time can be measured, and it is difficult to analyze the signal composition in advance; moreover, the existing evaluation methods do not impose boundary constraints on the target complex electromagnetic environment, and The target electromagnetic environment often has the characteristics of wide frequency coverage, large amplitude dynamic range, and multiple polarization directions, so that the existing evaluation methods are greatly limited in practical applications, and the credibility of the evaluation results is difficult to evaluate
