  author={Zhao Bin and Zhou Ke Jun},
  journal={2015 34th Chinese Control Conference (CCC)},
To solve the problem that the line-of-sight (LOS) angular rate extraction accuracy of strap-down seeker is usually affect by the measurement accuracy of attitude angular rate and the accuracy of attitude angle calculation, a new LOS angular rate filtering method aided by the attitude control rudder angle was proposed. First, the filtering equation of MEMS inertial measurement unit (IMU) was established based on the attitude dynamics; second, the Unscented Kalman Filter (UKF) was employed to… CONTINUE READING
