摘　　要：针对运动平台位置测量通常精度不高的问题,文章基于非合作目标的运动平台导航误差估计方法,将平台的导航误差建立为随时间一阶变化的模型,求解平台的运动参数,并使用线性模型拟合不同目标相对于不同平台的位置测量。通过对比参考平台与其他平台对相同目标运动参数估计的差异,求解平台的导航误差参数,并对平台运动参数进行校正。数值仿真证明了算法的有效性,并分析了测量次数对导航误差估计精度和目标定位精度的影响。In response to the problem of low accuracy in position measurement of motion platforms,a non-cooperative target based navigation error estimation method for motion platforms is studied.The navigation error of the platform is es‐tablished as a first-order time-varying model,and the motion parameters of the platform are solved.A linear model is used to fit the position measurement of different targets relative to different platforms.By comparing the differences in estimat‐ing the same target motion parameters between the reference platform and other platforms,the navigation error param‐eters of the platform are solved,and the platform motion parameters are corrected.Numerical simulations have demon‐strated the effectiveness of the algorithm and analyzed the impact of measurement frequency on navigation error estima‐tion accuracy and target positioning accuracy.
