基于雷达和成像传感器的融合跟踪

基于战术防空导弹的跟踪制导问题提出了一种利用雷达和成像传感器的融合跟踪方法。成像传感器获得的目标姿态观测，对目标机动十分敏感，而成像传感器得到和目标视线角观测十分精确，不存在角闪烁现象，数据融合技术充分利用了雷达和成顺的观测信息，显著地改善了机动目标的跟踪性能，大大减小了目标机动引起的脱靶量。

基于雷达和成像传感器的融合跟踪

A new 3-D fusion tracking system for an anti-air missile homing system based on radar and imaging sensor is developed. The attitude measurements from the imaging sensor is used to improve the tracking performance. Data fusion techniques are employed to get least-mean-squares estimates. Computer simulation results indicate that the tracking system greatly reduces the tracking errors compared with trackers without attitude measurements, and achieves small miss distances even when the target performs a big maneuver.
