A multi-platform bearing-only maneuvering target tracking algorithm based on joint estimation of time node
Aiming at the problem of surface and underwater bearings-only variable speed and directional target man-euvering detection and tracking,a multi-platform bearing-only maneuvering target tracking algorithm based on joint estima-tion of time nodes is proposed.The algorithm equates the maneuvering time of the target to an"unknown time node",and directly estimates the target maneuvering time and the motion elements before and after the target maneuvering based on the Taylor series motion element estimation method.The maneuvering detection feature is the iterative process of estimating the maneuvering time and estimating the iterative components of the maneuvering time.When the iterative process oscillates and diverges,or the estimated value of the maneuvering time is not within the observation time range,the target does not under-go maneuvering.The simulation results show that the algorithm has a maneuvering detection low false alarm rate and high tracking accuracy when tracking medium to long-distance sea variable direction and variable speed targets.
