根据相对运动学关系提出了一种天基平台对非己方目标的相对导航方法。基于测角相机和激光测距仪的组合测量方案,通过扩展Kalman滤波方法来估计天基平台与目标的相对位置和相对速度信息。在近共面轨道和近距离的假设下,给出了一种简化的导航算法,在目标轨道参数未知的情况下进行相对运动参数的估计,并获得了较高的导航精度。
According to the relative kinematics relationship, a relative navigation method of the non-own goal of the space-based platform is proposed. Based on the combined measurement of angle camera and laser range finder, the relative position and relative velocity of the space-based platform and the target are estimated by extending Kalman filter. Under the assumption of near-coplanar orbit and near distance, a simplified navigation algorithm is proposed, which estimates the relative motion parameters with unknown orbital parameters and obtains high navigation accuracy.
