| 摘 要： | 无线电双向比对法是当前进行高精度时间同步采用的主要方法,在时间同步处理过程中要扣除相应发射设备和接收设备的时延,包括发射设备时延和接收设备时延的设备收发组合时延准确性直接关系着无线电双向时间同步的性能。论述了设备收发组合时延与时间同步的关系,给出了用于设备收发组合时延测量的传递测试方法,分别进行了同源与非同源状态下的设备收发组合时延传递测试实验,实验结果验证表明了传递测试方法的可行性。

| Abstract: | TWSTFT is currently the main method of high precision time synchronization.The time delay of receive-transmit equipment should be subtract ed from the process of time synchronization.The accuracy of combined time delay of receive-transmit equipment is directly related to the performance of TWSTFT. The relationship between the time delay of receive-transmit equipment and the t ime synchronization is discussed,and the transfer testing technique of measuring the receive-transmit combined time delay is provided.Experiments with same sou rces and different sources are conducted to test the receive-transmit equipment combined time delay,and the results show the feasibility of the transfer test t echnique. |
