25245 在数值模拟中，均值、标准差等统计特性是评价数值仿真结果是否合理的重要依据。 The uncertainty in simulation results induced by the uncertain parameters of dispersive and lossy soil is quantified with the auxiliary differential equation (ADE) finite-difference time-domain (FDTD) method combined with gPCE．
25246 该方法结合辅助微分方程时域有限差分法与广义多项式混沌展开方法，对色散有损土壤模型的不确定参数所引起的仿真输出结果的不确定性进行量化表征，从而得到输出结果的不确定度。 To avoid the curse of dimensionality in modeling complex systems, the combination of uncertainties is incorporated into the new method to evaluate the interval of the uncertainty of the output.
25247 与传统不确定性分析方法蒙特卡洛方法相比，该方法计算效率更高，显著降低计算成本。 The results from the new method are compared against traditional UQ method Monte Carlo method (MCM). The new method shows its considerable advantage in the computational expense and speed．

Projector projects colored concentric circles to a calibration plane, on which an array of concentric circles is printed． The centers of the circles in image frame are identified with geometry constraints, with which the homographies between the calibration plane, image plane and projector plane are estimated.
25249 利用颜色信息分离投影同心圆和标定板标记图像，简化标定步骤减少图像采集数量; The method uses color information to separate the image of projected circles and that of the circle patterns on calibration plane, which reduces the number of required images and simplifies the calibration procedure.
25250 同时通过交比不变性实现同心圆自动匹配，避免人工干预。 To avoid manual intervention, cross-ratio invariance is used to match concentric circles automatically．

25252 现有的分选算法均或多或少地存在对复杂调制信号难以分选、分选正确率低、对低重频信号分选效果差以及实时性差等问题。 The existing deinterleaving algorithms have some problems such as difficulty in sorting complex modulation signals, high false alarm or false dismissal rate, poor performance on low repetition frequency signals, and poor real-time performance．
25253 本文针对以上问题，提出了一种基于多站时差和多参数信息联合的单脉冲信号实时分选方法。 In order to solve the above problems, this paper proposes a real-time single pulse signal sorting method based onmultistations time difference of arrival (TDOA) and multi-parameters information．
25254 该方法首先引入时差窗，对多站接收到的脉冲信号进行粗配对，分别得到多个可能与主站单脉冲正确配对的“脉冲对”序列;然后，利用脉内多参数信息对“脉冲对”进行精确匹配，获得真实配对的“脉冲对”，进而计算“脉冲对”对应的时差并得到“时差对”序列; Firstly, the time difference window is introduced to make rough pairing of pulse signals received by multi-stations to obtain multiple "pulse pair" sequences which maybe correctly paired. Then, the "pulse pair" is accurately matched by intra-pulse parameters to obtain the true "pulse pair" . Then, the time difference corresponding to the "pulse pair" is calculated and the "time difference pair" sequences are obtained．
