基于IC-SOR-DEN的无人机空战意图识别
UAV air combat intention recognition based on IC-SOR-DEN
在高度复杂且对抗激烈的空战环境中,无人机意图评估方法普遍面临融合规则主观性强、忽视相关属性时间关联性及缺陷信息处理手段不足的挑战。针对这些问题,提出了一种融合缺陷信息修正与主客观规则的动态证据网络方法。首先,着眼于连续型变量在时间维度上的强关联性,模块化构建了一个时空融合的证据网络模型。然后,通过引入长短期记忆网络(long short-term memory,LSTM)轨迹预测技术建立缺陷证据修正机制,显著提升信息的准确性和完整性。最后,基于统计计算的方法设计客观规则,并结合主观经验,构建全面且可靠的主客观规则库。基于上述改进进行4组不同方法的实战仿真试验,结果证实所提出的缺陷信息修正、主客观规则、“时-空”动态融合等机制在提升意图识别结果的精确度和可信性方面具有显著优势。
In the highly complex and intensely adversarial air combat environment, current unmanned aerial vehicle intention assessment methods generally face challenges such as strong subjectivity of fusion rules, ignoring the time correlation of relevant attributes, and insufficient defect information processing means. To address these issues, this paper proposes a dynamic evidence network method that integrates defect information correction and subjective and objective rules. Firstly, focusing on the strong correlation of continuous variables in the time dimension, a spatiotemporal fusion evidence network model was modularly constructed. Subsequently, by introducing the LSTM trajectory prediction technology, a defect evidence correction mechanism was established, which significantly improved the accuracy and integrity of information. Finally, objective rules were designed based on statistical calculation methods, and combined with subjective experience, a library of subjective and objective rules was constructed. Based on the above improvements, simulation experiments were conducted. The results confirm that the proposed mechanism of defect information correction, subjective and objective rules, and dynamic fusion have significant advantages in improving the accuracy and credibility of intention recognition results.
