Bounds Calculation Method of Electromagnetic Availability Zone of Radio Emission Source

The article deals with the problem of determining electromagnetic availability zone radio transmitter communication channel in UHF/VHF range on terrain map area. This was solved using well-known mathematical models signal propagation, depending characteristics specific Based wave algorithm, a bounds calculation method is proposed, digitized radiation pattern means. conducted calculations show effectiveness tasks assessing performance mobile and its security at local combat operations conditions operation an enemy reconnaissance receiver or interference system.
