Well, at point P, the velocityvector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
点P,速度向量,垂直于直线,所以该角的正弦值为。

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