| 摘 要： | 为了增强复杂电磁环境中航空集群战术网络的抗干扰能力,提出把同时收发认知抗干扰电台应用于航空集群网络节点,且每个节点采用改进能量检测方法进行干扰感知。在此基础上,分别研究了存在单/多个干扰源时的网络节点干扰感知性能,推导出干扰感知的虚警概率和检测概率的闭式表达。仿真结果表明,通过调节改进能量检测器的参数p,可以提高航空集群机载战术网络的干扰感知能力。

| Abstract: | In order to enhance the anti-jamming capability of aeronautic swarm tactical network in complicated electromagnetic environment, the simultaneous transmitting and receiving based cognitive anti-jamming radio was employed in aeronautic swarm network, and the improved energy detection method was proposed to jamming sensing. In the case of single and multi-jammer, the closed expression of false alarm probability was derived, the false detection probability and the optimal decision threshold of jamming sensing. Simulation results show that jamming sensing performance can be improved by adjusting the parameter p of the improved energy detector. |
