摘要:
为对基于雷达探测系统的舰炮弹道修正弹进行快速、准确的弹道解算及精度分析,通过建立舰船运动与雷达测量参数间的关系研究了舰船运动对弹道修正弹预报弹道落点的影响。建立了舰船摇摆角、航速、航向角及其升沉等因素测量误差对雷达测量弹道参数坐标转换精度影响的数学关系。结合扩展卡尔曼滤波预报弹道模型,计算分析了舰船运动中各因素测量误差对预报弹道落点的影响。计算结果显示:在同时考虑舰船摇摆角测量误差的情况下,与仅考虑雷达测量误差的计算结果相比较,雷达测量弹道参数的坐标转换误差和预报弹道落点误差增大了约1倍;在纵向和方向上,
Abstract:
To calculate the trajectories and analyze the accuracy of trajectory correction projectiles(TCP) fired on warships under radar detecting systems quickly and accurately,the relations between warship motion and radar measuring parameters are established to study the effects of warship motion on predicted trajectory falling points of TCP.The corresponding mathematic relations of influences of measurement errors of swing angles,speed,heading angles and heaving for warships on coordinate transformation precision of radar measured trajectory parameters are established.A prediction trajectory model is proposed using extended Kalman filtering,the effects of measurement errors of some factors during warship motion on predicted trajectory falling points are calculated and analyzed.The calculation results show that:compared with the calculation results of considering the measurement errors of radars only,the errors of coordinate transformation and predicted trajectory falling points of radar measured trajectory parameters increase by 1 times when the measurement errors of swing angles are considered simultaneously and increase by 0.5 and 2 times in range and azimuth directions respectively when the measurement errors of speed,heading angles and heaving of warships are considered simultaneously.
