利用导弹制导误差补偿规律修正不完全弹道测量的数据融合技术

论述不完全弹道测量的数据融合处理问题。在惯性器件天地关系一致的前提下，导弹惯性器件误差补偿量变化规律，就反映了飞行中制导工具误差的变化规律，即遥外差的变化规律。因此，可以利用补偿量视速度的变化规律约束条件，内插出不完全测量段落的遥外差数据，在建立节省参数的弹道估计的联合模型基础上，融合少量的高精度测元来解算弹道参数。落点验算表明：利用该方法计算的落点接近实际落点。

Data Fusion Technology for Correction of Incomplete Trajectory Instrumentation with Missile Guidance Error Compensation Rule

This paper discusses data fusion for incomplete trajectory instrumentation in aerospace TT&C technology. Based upon the consistency of inertial instruments between launch vehicles and ground equipment, the variation regularity of view-velocity, which comes from the real-time complement to the system error, exactly reflects the comparing tracking data with telemetry data. Then, using their difference and relevant restriction conditions, an economical parameter model that solves trajectory is established. Checking computations show that the method is correct, efficient and is adaptive to other incomplete measurement.
