TTNT为实时通信提供强有力支撑,针对TTNT数据链系统,研究了该系统的关键技术如多波束天线、一发多收、统计优先多址接入协议;搭建TTNT数据链的物理层到链路层的完整系统模型,厘清TTNT通信工作机制;考虑干扰对抗问题,设计多节点网络拓扑图,模拟TTNT数据链干扰攻防场景。仿真结果表明,所搭建TTNT数据链仿真系统在设计场景下具有合理的干扰对抗性能表现。TTNT技术研究与模拟仿真为数据链干扰对抗提供了数据依据和参考价值。
Tactical Targeting Networks Technology(TTNT)provides robust support for real-time communication.As for the TTNT data link system,such key technologies of the system as multi-beam antennas,single-input multi-output,and statistical priority multiple access protocols are initially studied.Subsequently,a comprehensive system model of the TTNT data link,spanning from the physical layer to the link layer,is constructed to elucidate the working mechanism of TTNT.Afterwards,the issue of interference confrontation is considered,a multi-node network topology is designed to simulate the interference attack and defense scenarios for the TTNT data link.The simulation results indicate that the constructed TTNT data link simulation system demonstrates reasonable performance in interference countermeasures under the designed scenarios.This technological research and simulation of TTNT offer a data basis and reference value for data link interference countermeasures.
