本文提出了把航迹、航速和航向误差等效为附加的测量噪声的方法。用两种统计参数估计方法估计了等效测量噪声的均值和标准差。求出了这些数字特征与地形的起伏标准差、粗糙度以及航速、航向误差之间的定量变化关系,为工程设计提供参考和依据。
This paper presents a method of equating track, speed, and heading errors with additional measurement noise. Two methods of statistical parameter estimation are used to estimate the mean and standard deviation of equivalent measurement noise. The quantitative relationship between these digital characteristics and undulating standard deviation, roughness, speed and heading error of the terrain was obtained, which provided a reference and basis for engineering design.
