现代战场环境日益复杂,随着空中机载装备技术的升级,海量多源异构传感器数据不可避免地出现信息不一致、不完备问题.传统面向机载多源传感器量测数据的融合处理方法忽略传感特征间的相关性,单依赖物理传感器的数据驱动形成封闭识别系统.考虑到专家认知、领域参数、属性规则等知识能以专家经验、规则约束等辅助认知形式在目标综合识别的模型构建、推理识别等环节起到指导作用,本文提出一种知识辅助的空中目标类型综合识别方法,利用上述知识,首先构建典型空中目标特征军事作战知识图谱,提取关键特征参数、识别规则阈值等建立目标辨识框架关联关系模型;然后在特征级识别、决策级识别层分别构建数据基本信任指派与证据冲突可信度;此外,针对证据出现高冲突情况制定时域融合规则,引入历史数据重构调整数据时序融合权重因子;最后在静态推理与动态融合下分层实现异构多源传感器的置信类型综合识别.本文在典型空中目标类型识别任务下识别准确率优于现有算法,验证了所提方法的有效性.
With the increasing complexity of modern battlefield environment and the upgrading of aviation equipment technology
massive multi-source heterogeneous sensor data inevitably appear inconsistent and incomplete problems. Traditional multi-sensor fusion method ignores sensor features correlation
and forms a closed data-driven recognition system of sensors. Whereas expert cognition
domain experience
attribute rules and other knowledge can instruct model construction and inference recognition of comprehensive target recognition in the form of expert experience
rule constraints and so on
this paper presents a method of knowledge assisted integrated identification of aerial targets. First of all
a military combat knowledge map of typical aerial target features is constructed
and key feature parameters are extracted to establish a target identification framework model. Then data basic trust assignment and evidence conflict credibility are constructed at recognition and decision recognition level respectively. Besides
time-domain fusion rules for high-conflict evidence is formulated to adjust timing fusion weights by using historical data. Finally
type recognition of multi-sensor is hierarchically realized through static reasoning and dynamic fusion. This study recognition accuracy is better than the existing algorithms in typical aerial target recognition tasks
demonstrating the effectiveness of the proposed algorithm.
