基于信息融合的空中红外小目标识别

针对空中红外小目标很难识别且可信度低的特点，结合已有的识别算法，设计出一种新的小目标识别方法。将小目标的灰度、速度信息作为主要识别依据，并在此基础上加入轨迹信息作为补充依据。在利用灰度、速度信息后仍无法识别的情况下，将轨迹信息加入证据，进行非平等的D-S证据信息融合。仿真结果表明，新方法在不增加传感器数目的情况下将识别置信度平均提高了125%。

IR small target recognition in sky background based on information fusion

For the difficulty of recognizing infrared small targets in sky backgrounds and its low recognition reliability,an improved method based on the unfair D-S evidential theory for small target recognition is presented combined with the previous methods. To improve the recognition confidence degree,the velocity and gray information of small targets is regarded as the major evidence,and the track information of the targets is treated as the supplement evidence. The proposed algorithm firstly recognizes the small...
