Which of the following statements is true regarding the main lobe of the RADAR signal?

The statement that the main lobe of the RADAR signal contains approximately 80% of the transmitted signal is accurate. The main lobe is the primary area of focus in radar technology and is responsible for capturing the majority of the signal energy that is used to detect and track objects. This concentration of signal energy is crucial because it enhances the radar's ability to accurately locate and identify targets.

In radar terminology, the main lobe is the region where the radar signal is most intense, and it typically encompasses a significant portion of the total signal emitted, often around 80%. This high percentage allows for effective detection and reliable measurement of distances and speeds of targets within its range.

The other statements do not properly reflect the characteristics of the RADAR signal's main lobe. For instance, the main lobe does not have a wider dispersion than the side lobes; rather, it is more focused, which increases its effectiveness in target detection. Additionally, the main lobe is designed specifically for the detection of both stationary and fast-moving objects, making it critical for a variety of applications in speed enforcement, aviation, and maritime operations.
