【摘要】：为解决传统雷达毁伤评估方法过于单一、评估准确性低的问题,引入D-S证据理论,提出了一种基于D-S证据融合的雷达毁伤评估模型。该模型将图像情报、电子情报、飞行员报告、无人机视频影像等多源信息作为证据体,利用证据向量余弦距离判断证据间的相似性,引入冲突比例因子决定冲突证据的修正方法,将修正后的证据代入D-S合成公式进行融合,从而降低了可信度低的证据给融合结果带来的不良影响。该模型充分利用了多源信息的优势,使融合后的雷达毁伤评估结果更加精确可靠。通过实验对比验证了该模型的有效性和准确性,为目标毁伤评估提供了一种新方法。
[Abstract]:In order to solve the problem that the traditional radar damage assessment method is too single and the evaluation accuracy is low, a radar damage assessment model based on D-S evidence fusion is proposed by introducing D-S evidence theory. Pilot reports, UAV video images and other multi-source information as evidence body, using the evidence vector cosine distance to judge the similarity between the evidence, the conflict ratio factor is introduced to determine the conflict evidence correction method. The modified evidence is put into the D-S synthesis formula for fusion, which reduces the bad effect of the low credibility evidence on the fusion results. The model makes full use of the advantages of multi-source information. The results of radar damage assessment after fusion are more accurate and reliable. The validity and accuracy of the model are verified by experimental comparison, which provides a new method for target damage assessment.
