| 摘要: |
| 在靶场弹道测量多目标雷达数据实时处理中，在预测目标状态之前需要进行目标航迹起始。传统航迹起始算法的可靠性受第一帧数据的不确定性影响较大。在进行高射频连发弹丸初速测量等高精度多目标弹道测量试验时，异常的航迹起始会导致弹道测量出现严重偏差。根据连发弹丸初速测量的特点提出了一种改进的航迹起始与跟踪算法。首先，选择检测效果最佳的数据作为起始数据进行航迹起始；然后，采用双向α-β-γ滤波的跟踪滤波方法获得弹道参数的最优估计。实测数据处理结果表明，改进的航迹起始与跟踪算法能够避免第一帧数据不确定性带来的影响，提高了雷达测量弹道参数的可靠性与稳定性。 |

| Abstract: |
| In the radar data real-time processing of trajectory measurement in the proving ground, track initiation is required before the target state prediction. The reliability of the traditional track initiation algorithm is greatly affected by the uncertainty of the first frame data. In the muzzle velocity measurement and high precision multi-target trajectory measurement test, abnormal track initiation results will lead to serious deviation of trajectory measurement. This paper presents an improved algorithm of track initiation and tracking according to the characteristics of projectile velocity measurement. First, the data of the best result is selected as the starting data for track initiation; And then, the optimal estimation of ballistic parameters are obtained by the bidirectional α-β-γ filter. The results of the measured data show that the improved algorithm can avoid the influence of the uncertainty of the first frame data, and improve the reliability and stability of the trajectory parameters. |
