Later , the corresponding matching algorithm is also proposed , which provides an excellent way to motion estimation problems concerning on the dominant points detection . in the multi - target motion states analysis systems , most papers only deal with the tracking problems 多目标运动分析系统不仅应具有对处于正常运动状态的可跟踪能力，更应具有对各种运动状态的辨识性及跟踪策略自适应性。
With the development of reducing noise technology and the advent of quieter targets , sonar faces up to the challenge of low signal - to - noise ratio detection while high detection performance is demanded by weapons ' s increasing range . moving target detection is two of first and last of sonar " four main tasks : detection , loacalization , classification and tracking / motion analysis of targets , which is the base of other two functions 随着降噪技术的发展，安静型目标的出现，声纳技术面临低信噪比的挑战，武器射程的增加又对声纳提出了更高的要求，关系到声纳的四大功能(检测、定位、识别和跟踪/目标运动分析)第一和第四个的运动目标检测任务重大，因为它对其余两个起着基础性的指导作用。
