Research on target location and tracking algorithm based on MIC
Aiming at the complex problem of underwater dual array azimuth-only target motion analysis,this paper proposes a azimuth-data association technology.In the air,Modified Iterative Correlation is performed by modifying the target and the observed data,and the target is tracked by Extended Kalman Filter algorithm and Unscented Kalman Filter algorithm.The simulation results show that the two filtering algorithms are suitable for real-time tracking of moving targets not only under water,but also in air after the spatiotemporal correlation(IATS)algorithm,but the Untracked Kalman Filter algorithm has better tracking effect.The tracking error curve and tracking track graph under different noise levels are given to verify the effectiveness and superiority of the algorithm.
