velocity filtering

The spatial filtering characteristics of the electrodynamic sensor were described quantitatively, from which the relationship between the frequency characteristics of the output signal of the electrodynamic sensor and particle velocity was obtained.

介绍了静电传感器的空间滤波特性，推导了颗粒流动速度与静电传感器输出信号频率特性之间的关系。

At the present, range correlation and velocity filtering processing methods are adopted in most of modern airborne pulse Doppler radar altimeters.

传统弹载脉冲多普勒雷达高度表大都采取了距离、速度二维选通处理方法。

In process of data processing, we used the techniques, such as filtering, edition surgical blanking, prediction deconvolution, fitting static correlation of first arrival time, and velocity analysis, and obtained a high-qualitative shallow seismic reflection sounding profile.

数据处理过程中采用了滤波、编辑切除、预测反褶积、初至时拟合静校正和速度分析等技术，得到了高质量的浅层地震反射探测剖面。

But when measurement data influenced by outliers, filtering convergence velocity becomes slow filter even diverges.

当测量值存在野值时, 滤波收敛变慢甚至发散.

Experiment results show that the filtering algorithm of restrain divergence can get more good filtering results than kalman filter, and obtain smaller errors of three-dimensional position and velocity.

实验结果表明在考虑加入抑制滤波发散算法后，可以获得比常规卡尔曼滤波器更好的滤波效果，获得的三维位置和三维速度的误差较小。

Filter aids such as HTK, GLF can speed up the filtering velocity and bring down the specific resistance, making the filter cake much regular and massy.

当添加助滤剂HTK、GLF后都能在一定程度上加快过滤速度、降低过滤比阻，使滤饼的成型更有规则、坚实，但是改善程度比较有限。
