提出了一种基于调制分量分析的雷达脉冲调制信号自主识别方法。与传统的自动调制分类方法提取调制特征的基础上的一个列表的已知模式,该方法分类调制的基本调制成分,包括连续频率调制,离散频率码和离散相位码的存在,在一个自治的方式。利用相位导数的短时一般表示法所得到的瞬时频率变化率曲线的突变特征是实现该方法的一个可行途径。该方法不仅适用于基本的雷达调制,而且适用于复杂的混合调制。理论结果和两个实验验证了该方法的有效性。
An autonomous method for recognizing radar pulse modulations based on modulation components analysis is introduced in this paper. Unlike the conventional automatic modulation classification methods which extract modulation features based on a list of known patterns, this proposed method classifies modulations by the existence of basic modulation components including continuous frequency modulations, discrete frequency codes and discrete phase codes in an autonomous way. A feasible way to realize this method is using the features of abrupt changes in the instantaneous frequency rate curve which derived by the short-term general representation of phase derivative. This method is suitable not only for the basic radar modulations but also for complicated and hybrid modulations. The theoretical result and two experiments demonstrate the effectiveness of the proposed method.
