Tactical Communication Network Node Immunity Of The Antenna Based On OPNET

The effect of network on military communications is transformational, theprominent characteristic of which is to interconnect the fighting factors by the network,such as the sensor, the weapon platform and the commander, in order to realizereal-time sharing of the battlefield information and to obtain the superiority ininformation, decision-making and action. To play to these strengths, theinterference-free connectivity between nodes is the primary prerequisite.The tactical communications networks are an important component of the militarynetwork. For the particularity of the battlefield environment, the tactical communicationnetworks do not rely on the fixed infrastructure, but they can also guarantee the freemovement of the war-fighters and the weapon platform. Due to the portability, thewireless communication has become the main connection mode of the tacticalcommunication networks. The wireless communication is an open type ofcommunication, and is vulnerable to the artificial or natural EMI. The importance of theantenna devices for wireless communications, should play an important role in theanti-jamming.However, due to technical, technological and other reasons, in thetraditional anti-jamming technology has been used less。In recent years, as technologycontinues to develop, the antenna is gradually paid more attention toanti-jamming.Directional antenna technology is an important part of antenna technologyis a new anti-jamming technology.It is used in tactical communication networks to thewireless node, how effective anti-interference, which is the focus of my research workcontent.In this paper, the southeast coast of the background of a tactical combat, based onnetwork simulation software OPNET, to build a local tactical communications network.For the network installation of a directional antenna, electromagnetic interference nodesconstructed to simulate the complex electromagnetic environment of the battlefield.Simulation run the network, testing a directional antenna in a complex electromagneticenvironment of the anti-jamming performance for the tactical communication networkresearch simulation anti-interference basis.
