在制导与跟踪系统中,雷达和红外成像传感器所固有的优缺点,决定了其自身的局限性,为综合利用上述传感器信息,提高目标跟踪精度,提出了一种基于雷达和红外成像传感器数据融合的交互多模目标跟踪算法,算法首先对红外图像进行处理,然后基于上述处理结果,利用交互多模算法对雷达观测信息进行目标跟踪,最后采用分布式数据融合算法得到最终目标的跟踪结果.在有效提高跟踪精度的同时,减少了运算量.

Radar and IR image sensor both have disadvantages because of their intrinsic characters. For improving the target tracking performance, an IMM target tracking algorithm is proposed to synthesize the information from both of them. In this algorithm, IR image was processed by digital image processing technology firstly. Then its result was fused with the radar information in the algorithm of IMM target tracking. At last, the final tracking result was got through distribution method. This algorithm can reduce operating time and improve the tracking precision.
