舰炮武器系统对大目标跟踪精度评估修正方法

随着技术的发展,舰炮武器系统的精度水平越来越高.在真实目标环境下一些影响系统精度评估的因素必须加以考虑,将具有相当外形尺度的目标作为点目标考虑势必带来系统精度评估的误差.针对大尺度目标,在目标坐标系下建立了目标外形尺度模型.利用目标坐标系和瞄准线坐标系之间的坐标变换,得到目标外形尺度在瞄准线法面上的描述,据此提出了一种大目标瞄准精度评估修正的计算方法.

Correction of Big Target Tracking Accuracy Evaluation Modification for Shipborne Gun Weapon System

With technology development,the tracking accuracy of shipborne gun weapon system has been also improved.Some factors which affect the system tracking accuracy evaluation must be taken into account under the condition of true target.The tracking accuracy evaluation for a big target assuming the target is a point in the space usually leading to evaluation error.The dimension model of the target is established in target frame.By using the transformation from the line of sight(LOS) to the target frame,the dimension model of the target is represented in normal plane of LOS.Finally,the big target tracking accuracy evaluation modification for shipborne gun weapon system is proposed in this paper.
