摘要
分析了垂线偏差产生的原因及其对导弹落点偏差的影响机理,利用制备好的垂线偏差网格数据,采取加权平均的方法计算发射点垂线偏差。介绍了目前的垂线偏差修正方法及其优缺点,提出通过修改初始姿态角的方法对垂线偏差的影响进行辅助修正,并建立了垂线偏差影响初始姿态角的数学模型。最后进行了弹道仿真,结果表明该方法能有效减小垂线偏差带来的落点偏差。
The cause of the deviation of vertical line and its influence on the distance between the point of fall and aim point are analyzed. Based on the prepared related data,the value of the deviation of vertical line on the launch point is calculate by the way of average weight method. The mathematic model of the influence of the deviation of vertical line on the initial angles is established. Modifying the initial angles is used to reduce this influence, The trajectory simulation results indicate this method is efficient.
