摘要
为提高时分复用光纤检波器阵列中延时参数的测量精度与效率,提出一种基于时分复用光纤检波器阵列的延时参数测量方法。该方法通过构建数据矩阵提取方差向量,利用脉冲模板函数进行相关运算,识别干涉脉冲的位置,从而计算延时参数。实验采用8时分复用阵列,在不同信噪比(SNR)条件下验证了方法的可靠性。实验结果表明:当SNR高于12 dB时,测量正确率达100%;SNR降至7 dB时,成功率仍超过98%;即使在-3 dB的极低信噪比下,仍能保持65%以上的正确率。
To improve the measurement accuracy and efficiency of time delay parameters in time-division multiplexed fiber optic detector arrays,a time delay parameter measurement method based on a time-division multiplexed fiber optic detector array is proposed.This method constructs a data matrix to extract variance vectors,performs correlation operations using a pulse template function,identifies the positions of interference pulses,and thereby calculates the time delay parameters.Experiments were conducted on an 8-channel time-division multiplexed array to verify the method's reliability under different signal-to-noise ratio(SNR)conditions.The results show that when the SNR is above 12 dB,the measurement accuracy reaches 100%.When the SNR drops to 7 dB,the success rate remains over 98%.Even at an extremely low SNR of-3 dB,the method maintains a correct rate above 65%.
