摘要
“速度+姿态”量测是目前比较理想的传递对准量测方案,但在工程应用时,存在矩阵计算量大、易受计算机速度限制等缺点。本文提出了“速度+姿态矩阵”量测,设计了快速对准卡尔曼滤波器,并对包括起飞过程的全程飞行轨迹传递对准进行了计算机仿真。结果表明:该技术不仅对速度、姿态航向等误差估计快速准确,而且有利于对惯性器件误差的估计和补偿,便于飞行员更好地捕捉战机。
＂Velocity - attitude＂ measurement is a relatively ideal transfer alignment measurement scheme. However, it still has some drawbacks in engineering application such as large matrix calculation cost and liable to the limit of computer speed. We put forward a ＂velocity - attitude matrix＂ measurement and designed a rapid alignment Kalman filter. Then we carried out computer simulation for the whole course flight track ineluding the attitude and takeoff. The result indicated that the method proposed can not only estimate the errors of velocity, heading quickly and accurately, but also be useful to error estimation and compensation for the inertial devices.
