射前遥测信息在地地导弹发射安全领域中的应用

Application of Pre-Launching Telemetry Information for Improving the Safety of Ground-to-ground Missile Launch

地地导弹惯性测量系统的稳定性及瞄准方位角的准确性直接影响导弹的发射安全。提出了用导弹射前遥测信息对其进行检验的方法。利用射前遥测信息,计算出重力加速度、地球自转角速度及瞄准方位角,通过比较计算值与实际值,完成惯性测量系统性能检测和瞄准方位角闭环检验,试验验证了该方法效果良好。

The stability of the inertial measurement system and the accuracy of aiming azimuth have a direct influence to the launch safety of ground-to-ground mssile. A new method of missile inspecting by its telemetry parameters is proposed, by which the acceleration of gravity, angular velocity of the earth rotation and aiming azimuth are calculated based on the pre-launch telemetry data. Then, the calculated values are compared with the practical values, thus the close loop inspecting of the inertial measurement system and the aiming azimuth are accomplished. The validity of this method has been proved by relevant experiment.
