美国防高级研究计划局(DARPA)首次成功演示先进反电子战计划,为种类各异、互不兼容的战术数据链在电子攻击中接收和传输数据提供支持。

DARPA项目工程技术人员提出“适应任务要求优化动态网络”(DyNAMO)计划, 旨在通过互不兼容的数据链路连接多个无线电网络,实现“在各种模拟竞争环境中所有数据链之间不间断的网络连接和跨域传输。”

通过将射频技术嵌入DyNAMO系统,将为“战术网络自动实时动态配置,以确保异构无线电节点(无论在地面、空中或海上)均可在竞争激烈战场环境协同作战”提供支持。

计划旨在无论使用哪种特定数据链,均能进行不间断的射频通信。

如果采用特定类型数据链节点传输的射频信号遇到频谱干扰或阻碍,该信号可跳转到另一个数据链节点上,类似手机信号可以不间断地从一个发射塔向另一个发射塔传输。


DARPA’s DyNAMO connects incompatible datalinks under electronic attack

The US Defense Advanced Research Projects Agency (DARPA), for the first time, successfully demonstrated an advanced counter-electronic warfare programme that enables disparate, incompatible tactical datalinks to receive and transmit data while in the midst of an electronic attack.

DARPA programme engineers developing the Dynamic Network Adaptation for Mission Optimization (DyNAMO) initiative were able to bridge multiple radio networks, transmitting across multiple domains, through several previously discordant datalink types to provide “uninterrupted network connectivity between all the datalinks under varying conditions in a simulated contested environment,” a 16 December agency statement said.

The radio-frequency (RF) technologies embedded into the DyNAMO system enable “automated, real-time dynamic configuration of tactical networks to ensure that heterogeneous radio nodes – whether on ground, air, or sea – can interoperate in a contested battlespace,” the statement added.

The idea behind the programme is to be able to have unbroken RF communications regardless of which specific datalink is being employed. If RF signals being transmitted from a node employing a certain type of datalink encounter interference or blockage along the spectrum, that signal can simply hop onto another datalinked node, in the same way a cell phone signal can ping from one transmission tower to another and not break communication.
