Adaptive tracking algorithm of curvilinear model

SUN Fu-ming,WU Xiu-qing,DUAN Man-ni(Department of Electronic Engineering and Information Science,USTC,Hefei 230027,China)  
In view of the problem of maneuvering target tracking, an adaptive tracking algorithm based on curvilinear model was presented.By filtering on the heading angle in real time to estimate angular velocity and angle acceleration of the object motion,an angular velocity estimation model with an inner layer of IMM was constructed so that the along-track and cross-track acceleration could be adjusted adaptively.The computation burden was reduced and the application range was extended.The simulation further proved the validity of this algorithm.
