基于"姿态矩阵"量测的机载导弹传递对准技术

"速度+姿态"量测匹配方案是目前比较理想的机载导弹传递对准技术.采用"姿态"量测时存在矩阵计算量大等缺点,在具体工程应用时更会受到计算机速度的限制,尤其是需要快速进行卡尔曼滤波计算时.引入了一种与"姿态"量测具有相同特点的"姿态矩阵"量测方案,设计了快速对准卡尔曼滤波器,并进行了仿真分析.结果表明是一种具有工程意义的实用快速传递对准技术.

The Airborne Missile Transfer Alignment Technology based on "Attitude Matrix" Measurement

As all known,"velocity and attitude"measurement match scheme is the relatively ideal airborne missile transfer alignment technology.There exists large amount of calculation in matrix computer and some other disadvantage when"attitude"measurement is adopted,it will also get the limit by the velocity of computer in the typical engineering application,especially in that need of rapid Kalman filtering calulation.This paper thinks about introducing the "attitude matrix"measurement that has the same characteristic as the "attitude"measurement,and designs the rapid alignment Kalman filter,and carries through the simulation analysis.The result indicates that it is a kind of practical rapid transfer alignment technology that has engineering meaning.
