摘　　要：将不同类型的情报信息高效回传至指挥中心是侦察型无人机的主要任务之一。针对不同类型的信息,须采用不同的传输体制,因此建立具有客观性、准确性、全面性的数据传输(以下简称数据传输)性能评价方法是保证机载信息高效回传的关键。鉴于现有评价方式更加注重提升指标、缺乏对传输体制的全面评估的问题,提出一种基于加权处理的无人机群数据传输性能评价方法。根据无人机信息的类型与特性,得到信息传输的侧重性指标、兼顾性指标以及次要指标,对不同指标进行权重分配,最终得到各项性能的得分以及综合得分。针对数据传输技术的几种典型方案,采用加权处理的方法进行综合性评价,更加直观地给出不同传输方案的优缺点。作为一种通用的评价方式,所提方法针对单一场景,能够对不同指标进行定量分析,指标的权值可根据实际需求灵活调整,综合得分结果更加直观且具有更高的可评估性,并且其评价方式具有对于多场景的推广性,可以通过改变权值大小的方式适应不同场景和不同信息类型下的评价需求,为无人机群在多场景下数据传输方案的选择和择优提供理论依据。Efficient returning of different types of intelligence information to the command center is one of the main tasks of reconnaissance unmanned aerial vehicle(UAV).Different types of information should adopt different transmission systems.Therefore,establishing a data transmission performance evaluation method with the features of objective,accurate and comprehensive is the key to ensure the efficient returning of airborne information.In view of the fact that the existing evaluation methods pay more attention to the improvement of indicators and lack of comprehensive evaluation of the transmission system,a method for evaluating the performance of UAV group data transmission based on weighted processing is proposed.According to the type and characteristics of UAV information,the emphasis index,balance index and secondary index of information transmission are obtained.The weight distribution of different indicators is carried out,and the performance scores and comprehensive scores are finally obtained.For several typical schemes of data transmission technology,the weighted processing method is used for comprehensive evaluation,and the advantages and disadvantages of different transmission schemes are presented more intuitively.As a general evaluation method,the proposed method can quantitatively analyze different indicators for a single scene.The weights of the indicators can be flexibly adjusted according to the actual needs.The comprehensive score results are more intuitive and more evaluable.The evaluation type of the proposed method can be promoted to multi-scenes.It can adapt to the evaluation needs of different scenarios and different information types by changing the weight size,which provides a basis for the selection and optimization of data transmission schemes for UAV group in multi-scenes.
