23806 对地下管道电缆等目标的几何特征估计在城市建设和市政基础设施维护中尤为重要，针对此类埋地细长良导体目标，该文提出一种基于瞬态电磁响应的管道目标长度与方位角估计方法。 It is particularly important to estimate the geometric features of buried pipe cables in urban construction and municipal infrastructure maintenance. For this kind of subsurface thin-wire structure targets, a method for estimation of the length and orientation of a target based on transient electromagnetic responses is proposed.
23807 建立了介电媒质中水平极化电磁波在布鲁斯特角入射下细长良导体目标后向散射回波时延差模型，通过分析瞬态响应时频分布，建立了其谐振态与目标长度的关系，并由此估计目标的长度。 In this method, a time delay difference model of the backscattering responses from such thin-wire structures illuminated by electromagnetic wave at Brewster's angle with horizontal polarization is established. By analyzing the time-frequency distribution of the transient responses, the relationship between the resonant state and the target length is established and the length of the target is estimated.
23808 利用瞬态响应早时部分首达回波与晚时部分谐振回波的能量变化趋势，判断电磁波到达目标两端点的时间顺序，再根据首达时间延迟差估计目标的方位角。 The energy change between the early time responses and late time resonances is applied to determining the time sequence of the arrival of the electromagnetic wave to the target. Then the target orientation is estimated by the time delay difference of early time responses.
23809 数值仿真结果表明在电场方向与目标轴线方向偏离不大的情况下，提出方法有效并且对噪声具有鲁棒性，适用于信噪比SNR5 dB≥的长度估计以及SNR>10 dB的方位角估计。 Numerical simulation results show that the proposed method is effective in the case of the direction of electric field close to the target axial direction. Meanwhile, the proposed method is robust to noise, and can be applied to length estimation for SNR5 dB ≥ and orientation estimation for SNR>10 dB .
23810 目前，用于室内定位的雷达技术为了达到高精度而使用高带宽的调频连续波，这样不仅对设备要求高且杂波干扰大。 The radar technology used in indoor localization prefers wide bandwidth frequency modulated continuous wave for high accuracy, yet this way needs specific device and suffers from clutters.

23812 在该方法中复杂的室内环境和人体变化的移动速度会造成频谱扩展，导致有效信号信噪比降低，能量发散甚至出现峰值误判，直接降低测速和定位的精度。 However, the receive signal spectrum spreads due to the complex indoor environment and the changing moving speed. The spectrum spread will leads to SNR reduction, energy divergence and wrong peak value, which decrease velocity measuring and localization accuracy.
23813 由此，提出应用于室内环境中的基于双频连续波比相测距的局部速度差补偿算法，以校准频域信号，获取高精度的速度与距离信息。 To improve the location accuracy, the frequency domain signal is calibrated with the proposed partial velocity deviation compensation algorithm in the dual frequency phase ratio localization.
