Method for calculating warhead fragment flying track under ultra-low-altitude combat condition

The invention provides a method for calculating a warhead fragment flying track under an ultra-low-altitude combat condition. By constructing a warhead fragment flying trajectory variable model underthe action of air resistance in a missile-target relative speed coordinate system, the precision problem that warhead fragments hit a target under the ultra-low-altitude combat condition is effectively solved, precision setting can be carried out for large-scale simulation calculation, and the balance between different calculation precision and calculation scales is met. Compared with a traditional warhead fragment flying trajectory calculation method, the method can accurately simulate and evaluate battle cooperation design, battle system design and weapon system battle effectiveness under the ultra-low-altitude battle condition. 本发明提出了一种超低空作战条件下的战斗部破片飞散轨迹计算的方法,通过构建在弹目相对速度坐标系内由于空气阻力的作用的战斗部破片飞散轨迹变模型，有效解决了在超低空作战条件下战斗部破片命中目标的精度问题，并可针对大规模仿真计算进行精度设置，满足不同计算精度和计算规模的平衡。相比传统的战斗部破片飞散轨迹计算的方法，该方法能够准确仿真评估超低空作战条件下的引战配合设计、引战系统设
