| 摘 要： | 为了提高导弹命中目标的精度,研究了GPS/SINS组合导航系统。以组合导航系统为应用背景,在常规Kalman数学模型的基础上,提出了改进的自适应Sage-Husa滤波方法。试验结果证明:在噪声的统计特性不能确定时,改进的自适应Sage-Husa滤波与常规Kalman滤波相比,导弹命中目标的圆概率误差(CEP)由原来的62m提高到21m。改进的自适应Sage-Husa滤波方法对提高GPS/SINS组合导航系统的制导精度和可靠性是十分有效的。

| Abstract: | To improve the accuracy of missiles targeting to study the GPS/SINS integrated navigation system. Integrated navigation system for applications in the background, in the conventional Kalman mathematical model based on the suggestions to improved self-adapting Sage-Husa filter. Simulation results explained that: In the noise statistical properties are not sure, the improved self-adapting Sage-Husa filter, compared with the conventional Kalman filter, The missile hit the target of circular error probable CEP ... |
