The common method to achieve jamming, as highlighted in the question, involves hanging chains under the vehicle. This technique disrupts the radar signal, making it difficult for the radar system to detect the vehicle accurately. When the chains swing or resonate with the radar signals, they can scatter and create noise. This interference prevents the radar detector from receiving a clear and unobstructed signal, thereby hindering its ability to measure speed or other relevant metrics.

In relation to the other methods, removing the RADAR unit from the vehicle does not constitute jamming; rather, it completely eliminates the radar's presence. Using a newer RADAR model would typically offer improved detection and tracking capabilities, thus making it less susceptible to jamming techniques. Employing multiple RADAR units may enhance detection coverage or accuracy but does not inherently contribute to jamming effects, which rely on interference methods rather than additional detection resources.
