The accuracy of radar readings is indeed affected by distance, and it tends to decrease as distance increases. This phenomenon occurs due to several factors inherent in radar technology. As a radar signal travels over a greater distance, it experiences attenuation, which can cause the signal to weaken. Additionally, longer distances increase the probability of interference from environmental factors such as weather conditions or objects between the radar and the target.

Also, the geometry of radar detection plays a role in accuracy. The further away an object is, the more difficult it becomes for the radar system to differentiate between closely spaced objects or to track the target accurately. This issue, combined with potential reflections and refractions of the radar signal, means that readings from greater distances are more prone to error.

Some options suggest that distance has a neutral or positive effect on accuracy, which does not align with the principles of radar technology. Understanding these concepts is crucial for radar operators to ensure accurate speed and distance measurements in their operations.
