Abstract:The network-centric operation is a new concept of information warfare. According to the concept of network-centric operation, the network-centric operation C4ISR architecture of the antiaircraft missile system is studied. The function units of combat zone are basic nodes of the architecture, the network-centric operation C4ISR architecture is composed of three logical networks, namely track-guide network, command-control(C2) network and weapon networks. The function and composition of the logic networks are defined. The architecture is valuable in network centric warfare of the antiaircraft missile system.
