Question: 1 / 400

What effect can rotating blades of fans have on RADAR readings?

They can improve the accuracy

They can act as false targets

Rotating blades of fans can indeed act as false targets in RADAR readings. When the blades rotate, they create moving reflectors that can scatter the RADAR waves. This scattering can lead to erroneous readings as the RADAR may interpret the rapidly changing reflections as objects, potentially obscuring or complicating the detection of actual targets.

In many instances, the rotation of the blades can produce a signature that is misidentified by the RADAR system, creating a false positive. This phenomenon can be particularly problematic in environments with multiple sources of interference, as the RADAR system attempts to track a range of movements. Understanding this aspect is crucial for interpreting RADAR data accurately, as it highlights how external moving objects can significantly impact the performance of RADAR systems.
