摘要
Abstract
In the radar data real-time processing of trajectory measurement in the proving ground,track initiation is required before the target state prediction.The reliability of the traditional track initiation algorithm is greatly affected by the uncertainty of the first frame data.In the muzzle velocity measurement and high precision multi-target trajectory measurement test,abnormal track initiation results will lead to serious deviation of trajectory measurement.This paper presents an improved algorithm of track initiation and tracking according to the characteristics of projectile velocity measurement.FirSt,the data of the best result is selected as the starting data for track initiation;And then,the optimal estimation of ballistic parameters are obtained by the bidirectional α-β-γ filter.The results of the measured data show that the improved algorithm can avoid the influence of the uncertainty of the first frame data,and improve the reliability and stability of the trajectory parameters.关键词
