Popis: In this paper, a method for inverse reading of curves for the expected level of electromagnetic field originating from broadcast transmitters, given in Recommendation ITU-R P.1546, is proposed. The proposed method is based on the application of artificial neural networks and enables efficient determination of distances for given field levels for the frequencies up to 4000 MHz. Accuracy of the method is illustrated by an example of curves related to the frequency 3050 MHz and several values of height h 1 not used for the neural model development.
