摘要 利用多普勒雷达的高精度测速信息,针对弹道导弹的再入过程,对弹道系数进行了仿真研究,分析了雷达的测量精度对弹道系数估计误差的影响。仿真结果表明,引入测速信息能大幅度提高弹道系数的估计精度,在一定的雷达测量精度下,基于弹道系数特性的识别速度快,精度高,简单直观,具有现实价值。 Using the Doppler radar＇ s high precision velocity information, the ballistic coefficient＇ s characteristic of reentry process is emulated and researched. The effect of radar precision to the ballistic coefficient estimate is analyzed. The result shows that the precision of ballistic coefficient is highly ad- vanced with the velocity information, and under a certain measurement precision of radar,it is fast, simple and intuitionistic to identify targets by using the ballistic coefficent characteristics. It is feasible to recognize the missile by the ballistic coefficient.
