摘要
红外运动小目标的检测,对提高红外成像系统的作用距离,具有重要意义。文中对先检测后跟踪(De-tect Before Track,DBT)和先跟踪后检测(Track Before Detect,TBD)两类红外运动小目标检测方法进行了对比,指出两类方法在目标检测中的适用场合。同时对红外目标检测领域存在的问题进行深入分析,最后指出了该领域可以深入研究的方向,以供后续开展红外目标跟踪与识别工作作为参考。
Infrared small moving target detection is important for improving the imaging distance in infrared im- aging system. The target detection methods of detect before track （DBT） and track before detect （TBD） were compared in this paper, and the application of which in variable fields was presented. Some important and lead- ing target detection methods were analyzed, and the existing problem was discussed. Furthermore, the trend of the development of infrared small target detection in future was mentioned and presented.
