中文摘要：
基于希尔伯特变换，提出了一种相位编码信号相位无模糊重构的脉内特征分析方法。该方法一方面利用魏格纳-威利变换对信号进行降噪处理，改善了在低信噪比下相位编码信号脉内特征识别和提取能力；另一方面对重构相位进行多阶差分处理来提高识别精度。仿真结果验证了该方法的正确性和有效性。
英文摘要：
A novel intrapulse characteristic of phase-coded signal analysis method is proposed, which based on Hilbert demodulation. On the one hand, the additive noise embedded in the signal can be reduced by using the Wigner-Ville distribution, which can improve the intrapulse characteristic of PSK signal recognition and extraction ability;on the other hand,multistage difference to restoral phase is used to increase the recognition precision. The simulation results confirm that this method is accurate and effective.
