A Road Networks Constrained GMTI Tracking Technique Using UPF
Bao Yang-hao · Modern Radar · 2007
A new approach to improve the performance of GMTI tracking using prior knowledge of road networks is presented.The problem of tracking an on-road target and a constrained nonlinear estimation problem are consistent essentially.Based on road networks constrained information,dynamic model is built,and a nonlinear/non-gaussian filter technique-UPF is introduced for filtering.Simulation results show that the proposal algorithm can improve the performance of tracking while reducing the computational requirements.
