雷达信号的识别是电子对抗的一个重要方面，是保证雷达对抗侦察和干扰设备有效发挥其作战效能的重要前提。在现代雷达对抗中，雷达信号更为复杂多变，造成了信号识别可信度的极大差异。如何衡量信号识别可信度，为实施有效干扰提供更为可靠的保证?文中针对电子战系统侦收信号的不确定性，以及现有雷达信号识别中识别可信度不能准确反映侦收信号与数据库中相应信号匹配程度的问题，提出运用数据融合的方法对雷达信号识别中的识别可信度进行确定。计算机仿真和实验测试均表明上述方法的有效性，并且已经很好地应用于实践。

Radar signal recognition is an important aspect of electronic countermeasures. It is the premise of ensuring the radar recon and jam equipment work effectively. In modern radar countermeasure, radar signal becomes more and more complex and changeful, resulting to the huge difference of recognition confidence. How to measure the confidence to provide reliable guarantee to effective jamming? Due to the indeterminativeness of signals in electronic war, and the problem that confidence in existing radar signal recognition cannot reflect the matching between recognized radar signal and library file, a new method is proposed to confirm confidence based on data fusion in this paper. The computer simulation and experiment test demonstrated that this algorithm is effective, and the method has been used in practice.
