recursive filtering meaning in Chinese

递归滤波
递推滤波

For large errors introduced by nonlinear state - space model in passive locating and tracking problems , various suboptimal recursive filtering algorithms are aralyzed and summarized , such as the extended kalman filtering ( ekf ) , the modified gain extended kalman filtering ( mgekf ) , the second order filtering and the adaptive extended kalman filtering ( aekf )
摘要针对被动定位跟踪中状态空间模型非线性程度较高所引发的滤波精度偏低的问题，分析和总结了已有的包括推广卡尔曼滤波( ekf ) 、修正增益的推广卡曼滤波( mgekf ) 、二阶滤波、自适应推广卡尔受滤波( aekf )等各种次优递推滤波算法的特点。
2 . the real - time processing technique of strong ground motion data is studied in this paper . based on the research of kanamori etc . , the relation between the design parameters of recursive filter and its corresponding low frequency cut - off frequency is obtained and quantitative phase adjustment is analyzed
本文在kanamori等人研究工作的基础上，发展了一套强震观测数据的实时处理技术，分析了递归滤波器设计参数q与所对应的低频截止频率f _ c以及相位校正的定量关系。
