Total levels of anthropogenic and natural microwave electromagnetic background in areas with intensive information servicing by constellations of low-orbit communication satellites

A technique for analyzing the averaged intensity of the electromagnetic background (EMB) created at the earth's surface by subscriber terminals of communication systems using constellations of low-orbit satellites has been developed. Using previously obtained results of the analysis of EMb created by radiation from the space segment of these systems, estimates have been made of the total levels of the ground anthropogenic and natural EMB. The results indicate that the radiation from subscriber terminals of these systems makes the main contribution to the ground EMB intensity, exceeding by several orders of magnitude other EMB components formed by both natural sources of microwave radiation and radiation from multitude of low-orbit satellites, changing the physical characteristics of the habitat and ground electromagnetic environment.
