High spatial resolution positioning algorithm based on BP neural network for long-distance distributed optical fiber sensing
为解决基于数字编码移相-积分测距系统中,因发送序列与本地序列之间的真实相位差非1 bit码长的整数倍而影响测量结果准确性这一问题,文中提出一种基于BP神经网络长距离分布式光纤传感高空间分辨率定位算法.该算法根据BP神经网络判断1 bit内细分程度并与传统算法相结合实现动态测距.实验结果表明,基于BP神经网络长距离分布式光纤传感高空间分辨率定位算法的长距离定位精度平均相对误差从0.23降低到0.035,弥补了空间分辨率与准确率受数字码本身局限性的问…查看全部>>
The real phase difference between the transmitted sequence and the local sequence is not an integer multiple of 1 bit code length,which affects the accuracy of the measurement results in the phase-shifting and integral ranging system based on digital coding,so a high spatial resolution positioning algorithm based on BP neural network(backpropagation neural network)for long-distance distributed optical fiber sensing is proposed.In this algorithm,the subdivisi…查看全部>>
