In a same direction scenario, how is the target speed calculated when the target is faster?

In a same direction scenario where the target vehicle is traveling faster than the stationary patrol or another vehicle, the target speed (TS) is calculated by adding the patrol speed (PS) to the closing speed (CS), then dividing by the speed of sound (SS). This approach accurately reflects the dynamics of the scenario, since both vehicles are moving in the same direction.

When the target is faster, the closing speed represents the difference in speed between the patrol vehicle and the target vehicle. By summing these speeds, you can determine how quickly the target is approaching or moving away relative to the patrol speed. This formula distinctly captures the relationship between the speeds involved and provides a straightforward calculation for determining the target's actual speed.

In cases where the patrol speed is lower than the target speed, simply adding the closing speed to the patrol speed gives the accurate target speed in the context of their motion. Thus, this formula is essential for accurate speed calculation in law enforcement radar or lidar operations.
