红外成像/毫米波雷达复合导引头信息融合研究

分析了红外成像/毫米波复合导引头的技术特点和工作状态,介绍一种红外成像传感器目标偏差角计算方法,针对红外成像/毫米波雷达复合导引头中平面毫米波雷达无法提供目标俯仰角信息这一特点,提出一种利用弹载测高仪提供的飞行高度推算出平面雷达俯仰角,并利用最优加权平均法对红外和雷达提供的信息进行融合,取得了较好的融合效果。

Study on data fusion of infrared imaging/millimeter wave radar combined seeker

Analyzes the technical characters and working states of IR Imaging/MMW Radar combined seeker,introduces the method of calculating the angle between target and IR imaging sensor.Since the plane MMW Radar cannot supply the pitch angle of target,in this paper,using the altitude supply by altitude indicator in the missile,a new method is presented to calculate the pitch angle,and fuse the information got from IR and MMW system through the algorithm of optimal weighted mean,study shows that a better result can b...
