| 摘要: |
| 研究了一种利用信号谱相关特性对周期平稳通信信号进行时差估计的方法。研究表明，谱相关时差估计方法较之经典的广义互相关(GCC)法具有更强的抗干扰能力，在多辐射源环境下，该方法可以无模糊地估计各个辐射源的时差。 |

| Abstract: |
| This paper studies the TDOA estimation method using the characteristics of cycle stationary communication signal.The study indicates that the TDOA estimation method based on spectral correlationl has better anti-jamming ability than the classical method of GCC,and this method can obtain the TDOA of each emitter unambiguously in the environment of multi-emitters. |
