摘　　要：基于防空武器系统的跟踪制导问题提出了一种利用雷达和光电传感器的融合跟踪方法。雷达能探测目标的斜距、方位角和高低角 ,光电传感器能较精确地探测目标的方位角和高低角 ,数据融合技术充分利用了雷达和光电传感器的观测信息及目标运动的特征信息 ,能显著改善系统机动目标的跟踪性能 ,提高武器系统的命中率。A new integrated tracking system for an air defense weapon system based on radar and photoelectric sensor is developed. Radar measures slant range, azimuth and elevation, and photoelectric Optical sensor measures azimuth and elevation accurately. Data fusion techniques are employed to get maximum likelihood method estimates. The fuzzy reasoning method is used to improve the tracking performance. Computer simulation results indicate that the proposed tracking system greatly reduces the tracking error when the target performs a big maneuver.
