Worst-case estimation of electromagnetic background near ground surface created by heterogeneous radioelectronic environment

Abstract

The practical method of worst-case estimation of the total electromagnetic background near ground surface cre- ated by different radio systems is offered. This method takes into consideration heterogeneity of radioelectronic environment formed by the full set of stationary and mobile transmitters of different radio services, and peculiarities of radio wave propaga- tion on different distances between transmitters and observation point, and of statistical features of electromagnetic fields in ob- servation point generated by these transmitters. The presented method allow to estimate the fundamental upper bound of elec- tromagnetic background total intensity created by heterogeneous radioelectronic environment, directly on the basis of estimation of the total electromagnetic loading on territory as the total equivalent isotropic radiated power of full set of transmitters of all services falling to the unit of the area of considered territory. The presented results ensure the facilities of EMC diagnostics and design of ultra wide band radio systems using nonsine radio waves, and cognitive radio systems using frequency bands on the secondary basis, and of support of the acceptable electromagnetic environmental conditions in populous areas.
