| 摘 要： | 介绍了Unscented Kalman滤波及其空间飞行器被动测距中的应用。Unscented Kalman滤波通过设计少量的sigma(抽样)点，计算这些点经过非线性函数的传播，获得滤波值基于非线性方程的更新。Unscented Kalman滤波避免了广义Kalman滤波等线性化方法的缺点，并提高了滤波精度。

| Abstract: | This paper introduces Unscented Kalman Filter (UKF) and its application in bearing-only ranging of space targets. In Unscented Kalman filtering, the updating of the filter based on the nonlinear state space equation is realized by designing a few sigma (sample) points and calculating the propagation of these sigma points via non-linear functions. UKF avoids the limitations of other linear methods such as extended Kalman filter and gives a more accurate result. |
