Real-time processing of tracking data of maneuvering target in beacon-mode
信标模式机动目标跟踪数据实时处理

When tracking the maneuvering target in beacon-mode, the accuracy of track estimation is always deteriorated by the system error in beacon-mode measurements. To deal with this problem, a novel method for estimating the target trajectory is proposed by augmenting the state vector with a system error element in target moving model, and adding this system error factor to the measurements equation. An Unscented Kalman filter is employed for estimating the system error and track the target. Simulation results show that the presented method can track the target with desired accuracy either in beacon-mode or in response mode.
