Theoretically? Yes

Realistically? No

The unit being used to measure relative speed/distance is a portable handheld device. The crucial element necessary in the formula you offered, to be admissable in evidence in court, would require an extremely accurate way to measure the precise angle between the two vesssels being read in order to interpret their correct separation. Since this particular LIDAR unit has no way of determinig that angle the formua would have to rely on the best guess of the officer, hardly admissable in court.
