A radar operator determines if a speed reading is valid primarily by ensuring that the radar system was calibrated and properly aimed at the target. Calibration of the radar equipment is essential because it ensures accuracy; if the radar unit is not calibrated correctly, it could give false readings. Proper aiming is also crucial—if the radar is not focused on the intended target, it may pick up reflections or interference from surrounding objects, leading to inaccurate speed measurements.

Collectively, these two factors establish whether the speed reading accurately represents the target vehicle's speed. Proper calibration and aiming eliminate potential errors that could arise from external influences or equipment malfunctions. Thus, without attention to these aspects, the integrity of the speed measurement could be compromised.
