How can reflections affect radar speed readings?

Reflections can significantly impact radar speed readings by causing false or inaccurate results. When radar waves are emitted, they bounce off objects in the environment before returning to the radar unit. If these reflections come from unintended sources, such as stationary vehicles, buildings, or even moving vehicles in close proximity, they can interfere with the measurement of speed.

For instance, if the radar detects a reflection from a vehicle that isn’t the target vehicle, it may calculate an incorrect speed based on the reflected waves instead of the intended target. This can lead to errors in law enforcement speed enforcement efforts or traffic studies. Thus, understanding how reflections can distort the true reading is essential for proper use and interpretation of radar technology in speed detection.
