angle of velocity vector
常見例句
- Well, at point P, the velocity vector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
點P，速度向量,垂直于直線，所以該角的正弦值為。 - 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.
針對平面攔截問題，選擇導(dǎo)彈和目標之間的相對速度矢量與導(dǎo)彈-目標視線之間的夾角（稱為相對航向誤差角）作為將要被控制到零的輸出。
