What is the shadowing effect in RADAR technology?

The shadowing effect in RADAR technology occurs when large objects, such as vehicles, obstruct the radar waves, causing difficulties in detecting the speed and presence of targets positioned behind or to the side of the obstruction. When these large vehicles are in front of the RADAR, they can block the radar signals, which may create an illusion that the targets behind them are moving at higher speeds or are not present at all. This phenomenon is particularly relevant in traffic situations where larger vehicles can mask the signals of smaller vehicles.

Understanding this effect is important for operators to accurately assess and interpret RADAR data, ensuring that speed measurements are not misrepresented due to the presence of larger vehicles in the RADAR's line of sight. By being aware of the shadowing effect, operators can better account for potential discrepancies in the data they are analyzing.
