基于弹速测量的弹道辨识技术

Ballistic Discrimination Based on Missile Velocity Measurement

在电磁干扰愈加普遍的现代战争中,用测量弹速的方法进行弹道辨识,目的在于研究一种抗干扰能力强,弹道预测准确度高的方法。通过研究涡轮发电机的频率输出特性和迫击炮弹的弹道特征,介绍了一种在标准气象条件下将涡轮发电机作为速度传感器测量特定点的弹道速度,进而通过迭代法确定初速与射角的弹道辨识方法。对非标准气象条件下的风速、气温、气压等因素的影响做了全面的分析,分别运用选点法和系数法对非标准气象条件下的风速、气温、气压等进行了修正,形成了比较完整的方法体系。

For ballistic discrimination by missile velocity measurement, a new method with high anti-interference performance and accurate ballistic predetermination was put forward. By researching on output frequency characteristics of turbine alternator and exterior ballistic fea- ture of mortar shell, a method of acquiring mortar shell＇ s original speed and firing angle was given based on turbine alternator as speed sen- sor to measure the ballistic speed of specific point. The effect of wind speed, atmospheric temperature and air pressure under nonstandard meteorological condition were deeply analyzed, then the method of selected and factor correction method were separately used to correct their effect for the integrated method system.
