What is a common issue that can lead to inaccurate radar readings?

Misalignment of the radar unit is a common issue that can lead to inaccurate radar readings because the effectiveness of radar technology relies on the precise direction in which it is aimed. If the radar unit is not correctly aligned with the target vehicle, the readings can reflect incorrect speeds due to the angle of incidence. Proper alignment ensures that the radar waves are directed straight toward the target, allowing for accurate measurement of speed.

When the radar is misaligned, it may not effectively capture the velocity of the vehicle directly in its path, potentially leading to skewed results. This misalignment can occur due to various factors, such as improper installation, vibrations from the vehicle it is mounted on, or environmental changes. Therefore, ensuring that the radar unit is properly aligned is crucial for maintaining the accuracy of speed measurements.
