为了对有源雷达组网方式进行识别,该文利用Dempster-Shapher(D-S)证据理论适于解决信息序贯融合问题的特点,提出一种基于多源信息融合的有源雷达组网方式序贯识别方法。首先对侦察获取的有源雷达和通信电台信息进行特征提取,然后结合专家系统计算特征向量与雷达组网方式的匹配度,最后通过一种改进的相对加权融合算法进行证据修正融合,实现了对4种常见有源雷达组网方式的识别。仿真结果表明了该方法的有效性。
In order to identify the netting type of active radar networks, the Dempster-Shapher (D-S) evidence theory is applied to solve the problem of sequential information fusion, and a sequential method for netting type recognition of active radars is presented based on multi-source information fusion. Firstly, features are extracted from the information of active radars and communication transmitters, which is obtained by reconnaissance equipments. Then the matching degrees between feature vector and different radar netting types are calculated combining with expert system. Finally, identification of 4 ordinary netting types of active radars is implemented by evidence modification and fusion using an improved mutual weight combination algorithm. Simulation results show that the proposed method is applicable and effective.
