摘要
通信资源是制约无人机集群作战的重要因素,不同的自主性等级下,无人机集群的通信量不同。为了估计无人机集群不同自主性等级下的通信量,采用理论分析与建模仿真相结合的方法,在搜索机动目标的背景下对不同自主性等级的无人机集群的通信量进行估计。结合搜索机动目标的背景对无人机集群不同自主性等级下的通信行为进行建模,而后通过仿真实验得到通信量分布数据,采用平均值法和排队论法两种方法对通信量进行估计,并用统计复用的方法对排队论方法进行修正。结果表明:实时图像处理技术是最需要关注的无人机集群自主技术,带来的通信资源节约效益显著。在通信量估计的过程中,均值法反映了理想的情况,排队论法更能反映实际的情况。在多点接入、统计复用的情况下,采用修正后的排队论法能进行更准确的估计。
Communication resources are an important factor that restricts UAV cluster operations.Under different autonomy levels,the communication volume in UAV clusters is different.In order to estimate the communication volume of UAV clusters under different autonomy levels,a method of combing theoretical analysis and modeling&simulation is used for estimating the communication volume of UAV clusters with different autonomy levels in the context of searching for maneuvering targets.Based on the background of searching for maneuvering targets,the communication behavior of the UAV cluster under different autonomy levels is modeled,and the communication distribution data is obtained through simulation experiments.The average value method and the queuing theory method are used for measuring the communication volume,and statistical multiplexing method is used to modify the queuing theory method.The results show that real-time image processing technology is the autonomous technology of UAV clusters that needs the most attention,and it brings significant benefits in saving communication resources.In the process of estimating the communication volume,the mean value method reflects the ideal situation while the queuing theory method can better reflect the actual situation.In the case of multi-point access and statistical multiplexing,the revised queuing theory method can be used for more accurate estimation.The estimation method of UAV cluster communication volume adopted in this paper can provide reference for related research in the future.
