Influence of the size of USAN filter to the performance of detection and the selecting of the threshold of gray difference was analyzed. The leaving of the background clutter was eliminated by the gray distribution difference of target and background clutter.
其中分析了USAN滤波模板大小对检测性能的影响，探讨了灰度差门限的自适应选取方法，并根据目标和背景杂波在灰度分布上的差异，进一步剔除背景杂波的残留。
In view of the target properties and USAN principle, the stable tracking of targets is carried out through eliminating noise disturbance by using the characteristic parameters of target, the uniformity and continuity of target movement.
针对弱小目标的目标特性，按USAN原则进行目标检测，利用目标的特征参数及目标运动的一致性、连续性排除噪声干扰，实现对目标的稳定跟踪。
