摘要
建立了精确制导炸弹MINS/GPS组合导航数学模型。针对扩展卡尔曼滤波存在的问题,研究了非线性滤波,提出了一种新的滤波算法——混合卡尔曼粒子滤波,并应用于组合导航系统定位。仿真结果表明:混合卡尔曼粒子滤波能有效提高组合导航系统的精度和可靠性。
to establish the mathematical model precision bombs MINS/GPS integrated navigation.Aiming at the existing problem of extended kalman filter, the nonlinear filtering, this paper proposes a new filtering algorithm -- mixed kalman particle filter, and applied to the integrated navigation system positioning.The simulation results show that the hybrid kalman particle filter can effectively improve the accuracy and reliability of integrated navigation system.
