| 中文摘要 |
| 信标模式下的机动目标测速数据存在较大时变系统误差, 导致目标飞行弹道解算精度降低. 针对此问题, 本文通过增加表征系统误差的分量项, 对机动目标运动模型的状态向量扩维, 并将系统误差引入到测量方程中, 提出一种弹道估计新算法. 利用无迹卡尔曼滤波计算跟踪目标的轨迹, 同时估计系统误差. 仿真试验表明, 该方法无论在应答或信标模式下都可以解算出满足精度要求的弹道. |
| 英文摘要 |
| 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. |
