摘要: |
介绍了卫星测控站纯侧音测距系统次侧音提取及相位匹配的一种新方法:基于正交双通道相关原理的数字相关相位估值法。经实验验证,与以往采用的锁相环法和最大似然判决相关法相比,捕获时间明显缩短。 |

Abstract: |
In this paper,a new approach on side tone acquisition and phase match of TT&C station is suggested.On the basis of orthogonal correlation,Digit correlative estimation acquisition is much shorter than conventional PLL and maximum likehood decision correlation. |
