空间非合作目标在轨主/被动融合跟踪方法
Tracking Method of Space Non-cooperative Target with Active/Passive Fusion In-orbit
摘要
Abstract
For the problem of tracking long distance in-orbit non-cooperative point target, a synergy tracking algorithm of active/passive fusion system is given. Using Unscented Kalman Filter(UKF) algorithm based on passive sensor and intermittent-working mode of radar, the state information of non-cooperative target is established, using angle's measurements provided by the optical camera and intermittent range's measurements provided by the radar to estimate position and velocity of the target. The non-cooperative target's state information can use as the initial orbit data for autonomy space operations. Simulation results indicate that the point target can be tracking consciously based on UKF algorithm when the state error and measurement noise are changing, and intermittent range information provided by radar can get better tracking accuracy.关键词
