Maximize the timeofflight and you point a cannon like this.
让飞行时间最大化,你像这样瞄准一门大炮。

They fit one distribution to the other, and when they line up that gives them the timeofflight, and thus the speed.
他们拟合这两个分布,如果它们吻合则能给出飞行时间,因此飞行速度。

From the return pulse, LOLA determines the timeofflight which, accounting for the speed of light, reveals the distance from the spacecraft to the lunar surface.
