What does the term "scanning effect" refer to in RADAR technology?

The term "scanning effect" in RADAR technology specifically involves how the radar interacts with moving targets and objects, particularly when calculating the speed of those targets. When the target moves, the radar may struggle to accurately assess its speed due to the Doppler effect and how the radar beams are processed over time. This misjudgment can occur especially with fast-moving objects or when the radar is not optimally aligned with the target's path, leading to incorrect speed readings.

Understanding the scanning effect is crucial for radar operators as it informs them of the potential for erroneous speed measurements when monitoring vehicles or other fast-moving objects, and it highlights the importance of proper radar setup and calibration to minimize these inaccuracies.
