| 摘要: |
| 根据chirp 信号在模糊域的特点, 本文提出了线性核时频表示方法。这种方法在提高分辨率、消除交叉项以及抑制噪声等方面都具有较高的性能。理论分析和实验结果都证实了这种方法的有效性。 |

| Abstract: |
| In this paper, the Linear Kernel TFR is proposed according to the AF of the sum of chirp and its delayed version. The method enables us to obtain high time and frequeney resolution while suppressing cross-term and minimizing the noise in the signal. Analytical and practical demonstrations have proved the validity and applicability of the proposed method. |
