Maneuvering Target Tracking based on Extended Kalman Filter
Qinkun Xiao · Fire Control and Command Control · 2009
The curve fitting and simulation research of extended Kalman filter aiming at the problem of high-speed flight target tracking is studied.Mathematical model of target tracking,the parameter and state equation of system are established thus linear Kalman filter is extended,filter model is expanded in form of Taylor series near the estimated value of independent variable of function and the Jacques matrix is attained by derivation.The function of extended Kalman filter about this problem is acquired based on obtained observation and system systematic errors.The simulation results illustrate its effectiveness.
