摘要
采用阻力系数多段样条描述法和非常规炮弹弹道数学模型,建立弹丸阻力系数辨识模型。阻力系数辨识程序通过其数学模型,用雷达测速、气象和其它初始参数,多段样条提取阻力曲线,以及从亚音速到超音速拟合阻力曲线来辨识弹丸的阻力系数。
Identification model of drag coefficient for projectile was established by using the multi-section spline describing method of drag coefficient and ballistic mathematical model of unconventional projectile, The drag coefficient of projectile was identified with the identification program of drag coefficient through the mathematical model,extracting drag curve through measured velocity data from radar,and fitting the drag curve from subsonic transonic to supersonic.
