航空通信频率极易受到战场复杂电磁环境的影响。针对航空通信频率干扰普遍情形,提出了一种基于排队论的航空通信频率干扰修复资源调度方法。首先,分析了航空通信频率干扰问题,并从航空通信网络角度对频率干扰等级进行界定;然后,分析了实时、非实时频率资源调度模型,并以此为基础构建了混合频率资源调度模型,对其运算流程进行详细阐明;最后,对2种不同算例条件下混合频率资源调度模型的系统运行指标进行计算分析。结果表明:混合频率资源调度模型能够较好适应具有等级差异通信链路干扰修复情况,且不同频率资源调度子系统的数量配比对于混合频率资源调度模型的系统运行指标存在差异性影响。

Aeronautical communications frequency is vulnerable to interference under the war-field complex electromagnetic environment. Aiming at the common condition of aeronautical communication frequency interference, a method of resource scheduling of aeronautical communication frequency interference repairing based on queuing theory is proposed. Firstly, the frequency interference problem is analyzed, and the levels of frequency interference from the perspective of aeronautical communication network are defined; secondly, the real-time frequency resources schedule model and non-real time frequency resources schedule model respectively, and a hybrid frequency resources schedule model is structured on this basis, then the calculate processes of it is given in details; Finally, calculated and analyzed the system operation indexes under two different examples. The result showed that： the hybrid frequency resources schedule model could adapt the difference-levels communication link interference repairing better, and different number proportion of frequency resources schedule sub-systems could reach the difference effects for operation indexes of it.
