Track Fusion Methods Based on Arrival Angle of Radar Signals
SI Xi-cai · Journal of Projectiles.Rockets.Missiles and Guidance · 2004
Two methods of track fusion are proposed,which is the important part in object recognition of passive radar. The first one is the optimized fusion of observing value based on the principle of maximum likelihood estimate,the sec- ond one is the fusion of estimated value with the de-correlation based on restarted local estimate predicting filter being used.The results of emulating on computer show that the two methods are feasible and effective.The fusion of esti- mated value solves the correlation problem in track fusion and has higher accuracy of fusion than the first one.
