多传感器基于证据理论的机载雷达用途识别

雷达用途识别是分析雷达型号和进行威胁评估的基础。在简要阐述D S证据理论基本概念的基础上 ,较系统地论述了基于D S证据理论的多传感器机载雷达用途识别的信息融合方法。该方法同时采用多个传感器 ,并且每个传感器进行多个周期的测量 ,然后利用多传感器多测量周期的信息 ,基于Dempster组合规则 ,采用中心式融合算法 ,对机载雷达用途进行识别。识别实例表明 ,该方法识别结果令人满意 ,使原来采用单一传感器可能存在的无法识别或误识别等现象得到了明显的改善。

Multisensor Airborne Radar Usage Identification Based on Dempster-Shafer Evidence Theory

Radar usage identification is the base of the radar type analysis and threat evaluation. This paper introduces the Dempster Shafer (D S) evidence theory first, and then analyzes the data fusion method of multisensor airborne radar usage identification based on the D S evidence theory. In this method, we use the information of multi period measurement of multisenseor and apply the center fusion algorithm to identify the airborne radar usage. At last, an identification example is given, which illustrates that this method decreases the unidentifiable and illidentification probability of the single sensor system.
