【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 real-time processing of multi-target radar data in range ballistic measurement, The reliability of the traditional track initiation algorithm is greatly affected by the uncertainty of the first frame data. In the high-precision multi-target trajectory measurement experiments, such as the initial velocity measurement of the high-frequency continuous projectile, the reliability of the traditional track initiation algorithm is greatly affected by the uncertainty of the first frame data. Abnormal track initiation can lead to serious deviation in trajectory measurement. According to the characteristics of continuous projectile initial velocity measurement, an improved track initiation and tracking algorithm is proposed. The best detection data is selected as the starting data to start the track, and then the tracking filtering method of bidirectional 伪-尾-纬 filter is used to obtain the optimal estimation of trajectory parameters. The experimental data processing results show that, The improved track initiation and tracking algorithm can avoid the influence of the uncertainty of the first frame data and improve the reliability and stability of radar trajectory parameters.
