地空通信系统作为军事通信的重要组成部份,在作战中发挥着重要作用。为打赢信息化条件下的局部战争,发挥军事通信作为战场神经网络的作用。文中结合3G技术发展情况提出基于3G的地空通信组网方案,并对组网关键技术进行分析,最后利用OPNET网络仿真软件对组网场景进行仿真,为军事通信现存矛盾的解决开辟了有效途径。 Air-ground communication system, as an important part of military communications, plays an important role in the operations. In order to win the local wars under the condition of informationization, military communications should be given full play as the battlefield neural network. Based on the development of 3G technology, this paper puts forward the scheme of air-ground communication based on 3G and analyzes the key technologies of the network. Finally, it simulates the networking scenario by OPNET network simulation software, which opens up an effective way for solving the existing conflicts in military communications .
