带二次约束的容积卡尔曼目标跟踪算法
Target tracking algorithm based on cubature Kalman filter with quadratic equality constraints
摘要
Abstract
In order to improve the tracking precision of moving target with quadratic equality constraints, a target tracking method based on cubature Kalman filter for systems with quadratic equality constraints is proposed. Firstly, the posteriori estimate is obtained by using the cubature Kalman filter. Then through regarding the quadratic constraints as the measurement equation, a satisfied amendment is obtained for the posteriori estimate. Finally a simulation experiment is carried out to test the performance of the algorithm. The simulation results show that, compared with the traditional constraint Kalman filtering algorithm, the proposed algorithm has improved accuracy and stability of target tracking.关键词
