electromagnetic environment, electric field strength, regression analysis, two-dimensional quadratic objective functionAbstract
The current study was conducted by making a series of experimental measurements of the electric field strength E. The obtained results have been interpreted using the method of mathematical modelling because the object of study – electromagnetic environment (EME) is a multifactorial system. With the accepted limitation of considering the influence of only two factors (frequency and time intervals) a two-factor regression analysis was used. The processing of the obtained data was performed by two-dimensional quadratic objective function.
