| 摘 要： | 研究了一种识别辐射源脉内调制方式的方法。该方法运用分形维数和相像系数作为辐射源信号的脉内特征，提出了基于模糊综合评估获取特征的基本概率赋值，然后运用D-S证据理论进行多脉冲数据融合，从而识别辐射源信号调制方式的方法。基于本方法的辐射源脉内调制方式识别方法通过仿真试验表明，其正确率高，具有一定应用价值。

| Abstract: | The method is studied using fractal dimension and resemblance coefficient as intra-pulse characters of emitter signal to recognize intra-pulse modulation,which could obtain the basic probability assignment based on fuzzy synthetic evaluation.And the multi-pulse data fusion method is introduced with the Dempster-Shafer(D-S) evidence theory which is applied to intra-pulse modulation recognition of emitter signal.The effectiveness and value of the method in intra-pulse modulation recognition of emitter signal is supported by the simulation result. |
