Mathematical tool for operational assessment of radio-electronic reconnaissance capabilities in a forest area

Abstract

The record of current military conflicts reveals the increasing role of counteraction against technical reconnaissance equipment. Measures of comprehensive technical control are to be taken to counteract technical reconnaissance equipment involving a rapid rise in both technical reconnaissance equipment of foreign states, and radio-electronic equipment- protected facilities, recognition signs of which emerge in all physical fields. One of the most dangerous reconnaissance types is various mode-based RER (Radio-Electronic Reconnaissance). RER equipment is widely used on board of foreign airlines flying over the Russian Federation territory and in border areas. Analysis of the current status and development potential of RER equipment enables to define tasks that can be solved through this equipment during reconnaissance activities. Visual electro-optical reconnaissance is an equally dangerous type of technical reconnaissance and to counteract this there is radio-electronic equipment installed either within forest areas or nearby which makes difficulties in assessing reconnaissance accessibility of protected facilities by RER equipment. The article’s aim is to substantiate mathematical tool for operational evaluation of RER capabilities to obtain guarded data about protected facilities. The mathematical tool proposed for use is based on calculating the attenuation factor in radio-frequency line passing through a forest area, which enables operational assessment of RER capabilities in forest areas. It is based on calculation of the electromagnetic field near trees and calculation of power for diffused scattering and coherent field.
