Application of Kalman Fixed Interval Smoothing in Trajectory Correction

摘要

A Kalman fixed interval trajectory smoothing algorithm is established combining with the particle trajectory model, which is used to find a way to resolve the contradictions of one-dimensional modified projectile path correction while the flight trajectory of ammunition needs to be accurately estimated. This algorithm can effectively solve the problem of accurately extracting trajectory landing point from the measured data of ground reconnaissance radar, and can greatly increase the concentration of the ammunition. A numerical example is given to illustrate the effectiveness of the proposed method.
