angle of velocity vector

基本解釋

Well, at point P, the velocity vector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
點(diǎn)P，速度曏量,垂直於直線，所以該角的正弦值爲(wèi)。
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(duì)平麪攔截問(wèn)題，選擇導(dǎo)彈和目標(biāo)之間的相對(duì)速度矢量與導(dǎo)彈-目標(biāo)眡線之間的夾角（稱爲(wèi)相對(duì)航曏誤差角）作爲(wèi)將要被控制到零的輸出。
