What is a common cause for radar interference?

Radar interference commonly arises from reflections caused by other vehicles or surrounding structures. Radar systems operate by emitting radio waves that bounce back upon encountering objects. If there are multiple reflective surfaces in the vicinity, such as nearby vehicles, buildings, or bridges, they can create additional signals that the radar system interprets as separate targets. This can lead to confusion in target tracking and affect the accuracy of the radar readings.

In contrast, wind velocity, darkness, or low visibility do not directly interfere with the radar signals themselves, although they may impact the overall operating environment. Thermal imaging operates on a different principle and is not related to radar interference, as it relies on detecting heat rather than reflected radio waves. Therefore, the primary and most relevant cause for radar interference among the options is indeed the reflections from other vehicles or structures.
