火箭弹横向散布的弹道修正技术研究

在火箭弹主动段弹道辨识修正原理的基础上,提出了以脉冲矢量为修正方式,在弹道被动段设置修正火箭弹横向散布的推冲点,以实现修正弹道的方法.该方法根据在主动段末点立即进行一次修正后的炮弹落点的位置,沿实际弹道逐步寻找适当的推冲点.同时以122mm火箭弹为例,根据运动方程建立了其数学模型,并通过仿真证明了该方法是提高命中率的行之有效途径.

The Research of Trajectory Correction Technology on Transverse Errors of Rocket Trajectory

A correction method is offered to minimize transverse errors of rocket trajectory by properly using pulse vector in the negative trajectory based on the recognition of the positive trajectorys features.According to the position analysis to point of fall corrected only once at the end time of positive trajectory, proper correction times are worked out along the real trajectory. A mathematics model is also set up based on the flight equation to simulate the correction of 122mm-rocket trajectory, and through the computersimulation the correction method is proved efficient.
