Modeling of Jamming of the Radio Network with Air Repeater

One of the promising areas for improving the efficiency of military VHF radio networks is the use of repeaters on board UAVs. Air repeater, compared to ground one, allows to significantly increase the coverage area and connectivity of the radio network, to reduce transmitter power by providing direct radio-visibility between the repeater and almost all radios in the network. From the point of view of the jammer there are four possible ways of electronic suppressing of the radio network, using air repeater (AR), which include suppressing the receiver of the AR or terrestrial radios by terrestrial jammer or by the air jammer. The calculations of the expected levels of the useful frequency hopping signal and the noise barrier interference at the entrances of the receivers of the terrestrial radio and the airborne (aboard the UAV) repeater during jamming from terrestrial and airborne (from UAV) means of electronic warfare have been performed. The directions of increase of anti-jammingness of radio networks, using air repeaters, are determined.
