然后建立时域上关于搜索块与参考块之间运动矢量夹角的概率模型，对于帧间预测宏块通过聂曼一皮尔迅准则进行运动判决。

For Inter-MB, a temporally statistical modal with regard to vector angle was established and the moving object was detected by using the neyman-pearson criteria.

针对平面拦截问题，选择导弹和目标之间的相对速度矢量与导弹-目标视线之间的夹角（称为相对航向误差角）作为将要被控制到零的输出。

For the case of planar interception, the so called relative heading error angle between the relative velocity vector and the LoS (Line of Sight) is chosen as the output to be controlled to zero.
