What common mistake can lead to incorrect speed readings in radar technology?

Incorrect aiming or misalignment can significantly impact the accuracy of speed readings in radar technology. When a radar device is not properly aligned with the object being measured, the angle of incidence changes, which can result in an erroneous speed calculation. Radar technology relies on precise angles to ensure that the signals reflect correctly off the target, allowing for an accurate determination of speed based on the Doppler effect. If the device is aimed too high, too low, or off to the side, the reflected signal may not represent the true speed of the vehicle. Properly aligning the radar unit ensures that the radar waves are directed at the target vehicle in a way that gives an accurate reading.

While unit calibration, background noise, and stability provided by a tripod are important factors, they do not directly relate to the fundamental mechanics of how radar measures speed. Misalignment, on the other hand, directly influences the measurement outcome itself, making it a critical consideration in radar technology application.
