末自导 meaning in Chinese

terminal homing

( 3 ) on the basis of kalman filer algorithm and on the premise of two assumptions , namely , state estimation error of each sensor is dependent or independent , kalman filter weight fusion algorithm and modified track - to - track fusion algorithm are proposed , then improved algorithm is applied to the simulation of line - guidance and terminal - self guidance of torpedo
( 3 )基于卡尔曼滤波算法，在各传感器估计误差相互独立和不独立两种假设的前提下，给出了卡尔曼滤波加权融合算法，在此基础上，提出了修正的track - to - track航迹融合算法，并将改进后的算法应用于鱼雷线导加末自导系统的仿真研究。
