摘要
双向时间传递的测距方法通过计算对称路径电磁波空间传输延时完成距离测量,然而随着测距精度要求的提高,通信设备内部传输延迟的不确定性成为不容忽视的因素。针对大量采用基于FPGA光纤传输链路的通信设备,在现有通信测距方法的基础上提出一种FPGA弹性缓存延时不确定性的测量与修正方法,并通过试验验证了该方法的有效性。
The bidirectional time transfer ranging method calculates the range by measuring the electromagnetic wave transmission delay along a symmetric path.However,with increasing requirements for ranging accuracy,the uncertainty of transmission delays within communication equipment has become a crucial factor requiring consideration.Aiming to the adoption of the communication devices based on FPGA fiber-optic transmission links,a method for measuring and correcting the FPGA elastic buffer delay uncertainty is proposed,building upon existing communication ranging techniques.The effectiveness of the proposed method is verified through experiments.
