摘要
研究了由全捷联光电导引头和MEMS惯性测量组合进行制导的微小型导弹比例导引实现方法;提出一种采用数学解耦算法,并利用最小二乘拟合提取视线角速度的方法。数值仿真表明,该方法在抑制测量噪声、抗弹体姿态扰动等方面具有良好的性能。与常规的虚拟跟踪回路解耦相比,该方法具有更高的视线角速度输出精度。
In this paper,the implementation method of mini missile proportional guidance guided by combination of the strapdown photoelectric seeker and MEMS inertial measurement unit is studied;and a method of extracting line-of-sight angular velocity by using mathematical decouping algorithm and the least square fitting is proposed.Numerical simulations show that the method has good performance in suppressing measurement noise and counter attitude disturbance.Compared with the conventional virtual tracking loop decoupling,the proposed method has higher output accuracy of line-of-sight angular velocity.
