基于正弦波抽取的信号脉内调制识别算法

Signal Intrapulse Modulation Recognition Algorithm Based on Sine Wave Extraction

针对常用雷达脉内信号调制方式的时变矩在不同延时及共轭阶数下所呈现的正弦波抽取特性,将对脉内调制方式的识别问题转化为对正弦波检测的识别问题。计算机仿真结果表明,该算法无需接收信号的任何先验知识,在较低信噪比条件下可实现对常用雷达脉内调制方式的有效识别。

The recognition problem is converted into a sine wave testing procedure because the common signals modulated by different intrapulse modulation type reveal different sine generation properties by the different order moment in different time-varying delay and the conjugate of the order.Computer simulation results show that the proposed method is effective to recognize the common intrapulse modulation type signals at a lower signal-to-noise ratio and without any priori knowledge.
