What is the formula used in same lane, target faster mode?

In the context of radar speed measurement, particularly in the same lane, target faster mode, the correct formula is essential for calculating the target speed accurately. The formula you mentioned, which is expressed as TS = PS + CS/SS, combines the different components relevant to the measurement.

Here, TS stands for the target speed, PS is the patrol speed (the speed of the police vehicle), CS is the closing speed (the speed difference between the radar and the target), and SS stands for the speed of the stationary subject or the reference speed. This formula indicates that the target speed is derived from the sum of the patrol speed and the fraction of the closing speed over the stationary speed.

Understanding the operation of the radar in this mode is essential because it uses the relative speeds to discern the actual speed of a target vehicle when multiple vehicles are present in the same lane. The effectiveness of this mode relies on accurately determining how fast a target is moving compared to the radar unit itself, which is stationary in this context. Proper application of the formula allows operators to measure speeds accurately, which is crucial for law enforcement and traffic safety regulations.
