How does the Cosine Effect benefit the violator in stationary RADAR?

The correct answer highlights that the Cosine Effect can indeed alter the speed interpretation when dealing with stationary radar. This phenomenon occurs due to the angle at which the radar signal interacts with a moving vehicle. When a vehicle approaches or moves away from the radar unit at an oblique angle, the speed reading can be affected significantly.

In particular, if the vehicle does not approach directly towards or move directly away from the radar, the speed that is detected may appear lower than the actual speed of the vehicle. This can create a discrepancy where the observed speed is not an accurate reflection of the vehicle's true speed.

Consequently, the Cosine Effect can lead operators to interpret the speed of violators incorrectly, potentially benefiting those drivers by yielding lower speed readings than they are genuinely traveling. This aspect is crucial for speed detection operators to understand, as awareness of the Cosine Effect is essential for ensuring accurate speed measurements and enforcing traffic laws effectively.
