| 摘 要： | 提出对雷达信号进行时域倒谱分析,能够将卷积性或乘法性信号分量分离,进而分析出雷达信号的调制信息。计算机仿真表明,在低信噪比条件下,倒谱分析对线性调频信号和相位编码信号的调制参数都能够进行有效估计。 |
| 关 键 词： | 雷达信号 倒谱 调制识别 参数估计 |

| Abstract: | The radar modulation signals can be considered to be composed through the convolution of the carrier-operated signal and the modulation signal.Based on the theory of cepstrum transform,the radar modulation signal is decomposed logarithmically,where the relationships are converted to linear summarization.Then the components are separated through the filtering.These processes are helpful in distilling the signal modulation parameters and to further recognition.Finally,the simulation analysis is made with LFM ... |
