摘　　要：半捷联惯性测量系统能实时精确测量弹体的各种飞行参数,为常规弹药精确制导提供可能,半捷联惯性测量系统包含两块采集数据的采存模块,当系统运行时,由于两个采存模块采集不同步以及取点不统一导致采集的数据不是实时同步,从而无法对系统测得的数据进行解算,本文提出一个实时对齐方法,利用数据相关性,求出差的平方和的最小值即为最接近的值,实现数据对齐,为后续精确解算奠定基础。Semi-strapdown inertial measurement system can realize real-time accurate measurement of projectile flight parameter, and provide the possibility for the precise guidance of conventional ammunition, Semi-strapdown inertial measurement system includes two blocks of data acquisition sampling module. As for the two acquisition and storage module asynchronous sampling, and take some disunity, which leads to the collection of the data is not real-time synchronization when the system running. Thus, we are unable to calculate the system measured data. This paper presents a real time alignment method, use the data correlation, deduce the minimum value and for trav- el is the most close to the values of the square. Finally, we realize data alignment, which lay the foundation for fol- low up exact solution.
