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。
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 probabil- ity assignment based on fuzzy synthetic evaluation. And the multi-pulse data fusion method is intro-duced 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.
