导弹末区轨迹的单站定位测量

Trajectory Estimation for Missile in Terminal Phase Using Single-Station Location

通过对导弹末区轨迹单站定位测量方法所采用的位置测量方程和速度加速度测量方程的推导,介绍了导弹末区轨迹的单站定位测量原理。系统误差分析结果表明,影响导弹末区轨迹测量精度的主要因素是测量设备的方位角和俯仰角测量误差,而不是通常认为的激光测距误差。通过单站定位测量法与多站交会测量法之间的性能比较,论述了单站定位测量法的技术优势。

On the basis of derivation of position, velocity and acceleration estimation equations, the principle of trajectory estimation for missile in terminal phase using single-station location are presented. It is shown by the systematic error analysis that trajectory error is mainly determined by the measurement error in azimuth and elevation angle, rather than the laser ranging error which is normally taken into consideration. The technical advantages of single-station location are introduced by the comparison of the performance of the multi-station cross location and the single-station location.
