摘 要: | 研究利用导弹过靶前的测量数据解算脱靶量参数。针对导弹过靶时刻BDS(北斗系统)不能定位和测量数据丢失等问题,采用最优滤波平滑处理技术,建立过靶瞬间弹道外推数学模型,对导弹飞行轨迹外推,获得过靶时的完整弹道参数。为解决靶船上合作目标部位不一致问题,利用导弹射向、弹道偏角、靶船航向信息和靶船上BDS天线相位中心相对于角反射体中心的位置,对合作目标部位进行修正,解算相对于角反射体中心的脱靶量参数。通过建立过靶痕迹方向判别坐标系,利用脱靶量参数,判别导弹过靶痕迹方向性。测试数据处理结果表明该方法精度高,脱靶量精度达到0.5 m。

Abstract: | This study focuses on utilizing the measurement data of a missile in pre-hitting a target to compute the miss-distance parameters.In view that the BDS (Beidou navigation system) usually can not locate the missile at the moment of hitting a target ship and the measurement data is always lost,a trajectory forecast model is set up by utilizing optimum filtering technique to extrapolate the missile-flying ending position parameter.By using such parameters as missile shot angle,trajectory angle,ship course,and the relative position between BDS antenna phase center and triangular trihedral reflectors' center on a target ship,the BDS antenna phase center position is transferred into the triangular trihedral reflectors' center position for computing the miss distance.A coordinate system for identifying the hitting-trace direction is set up,and the miss-distance parameters are used to recognize the direction property of a missile's trace in hitting a target.Test results show that the proposed method has high accuracy,and the miss-distance error is no more than 0.5 m. |
