弹道修正中弹道诸元探测时间间隔的确定

TO DETERMINE DIFFERENT POINTS OF BALLISTIC MEASUREMENT FOR TRAJECTORY CORRECTION

弹道修正技术是减小弹道散布的一种新措施 .修正过程中首先要采用某种测试手段在飞行弹道上逐点进行诸元测量 .测点过密信息处理量大 ,测点过疏又引入较大误差 .为确定合理的测点密度进行了计算分析 ,并给出了确定最大测点间隔的界限判据 。

The trajectory correction is a new technique to improve dispersion of projectiles. A kind of measurement would be used to measure ballistic parameters on different points of trajectory for this correction. Too density of measurement points, the computation of data is difficult. Too less of measurement points, the error of prediction for trajectory correction may be significant. The suitable measurement points have be discussed in the paper and the criterion of the largest time between two points has been set up. The criterion is useful to research detailed performance of trajectory correction.
