【摘要】：在靶場彈道測量多目標(biāo)雷達(dá)數(shù)據(jù)實(shí)時處理中,在預(yù)測目標(biāo)狀態(tài)之前需要進(jìn)行目標(biāo)航跡起始。傳統(tǒng)航跡起始算法的可靠性受第一幀數(shù)據(jù)的不確定性影響較大。在進(jìn)行高射頻連發(fā)彈丸初速測量等高精度多目標(biāo)彈道測量試驗(yàn)時,異常的航跡起始會導(dǎo)致彈道測量出現(xiàn)嚴(yán)重偏差。根據(jù)連發(fā)彈丸初速測量的特點(diǎn)提出了一種改進(jìn)的航跡起始與跟蹤算法。首先,選擇檢測效果最佳的數(shù)據(jù)作為起始數(shù)據(jù)進(jìn)行航跡起始;然后,采用雙向α-β-γ濾波的跟蹤濾波方法獲得彈道參數(shù)的最優(yōu)估計(jì)。實(shí)測數(shù)據(jù)處理結(jié)果表明,改進(jìn)的航跡起始與跟蹤算法能夠避免第一幀數(shù)據(jù)不確定性帶來的影響,提高了雷達(dá)測量彈道參數(shù)的可靠性與穩(wěn)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 偽-尾-緯 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.
