摘要
Abstract
The great tracking error of radar to maneuvering target exists in aerospace measurement & control if the exterior trajectory of a launcher is calculated directly according to the measured value of radar because of the high random error. An IMM-UKF based maneuvering target tracking method of radar which satisfies the motion characteristic of the carrier rocket better is presented. The simulation result shows that the IMM-UKF algorithm has higher accuracy of exterior ballistic tracking than that of the methods such as direct calculation method of target trajectory and UKF filtering method based on single motion model. In ad-dition,the convergence velocity of IMM-UKF algorithm can meet the real-time requirement of exterior ballistic tracking in aero-space measurement & control.关键词
