What percentage of the central core (Main Lobe) of RADAR is typically used?

The central core or main lobe of a radar signal is the area that primarily accounts for the effective detection and measurement of targets. Typically, around 80% of the energy from the radar signal is concentrated within this central core. This percentage is crucial because it determines the radar's sensitivity and accuracy in detecting objects, particularly in evaluating the speed of vehicles in speed enforcement situations.

This 80% focus also relates to the radar's ability to maintain coherence and minimize interference, ensuring that the measurements taken are as precise as possible. Radar operators are trained to understand this aspect so they can position themselves correctly to optimize performance. By concentrating on the main lobe, operators can reduce the likelihood of false readings caused by noise or reflections from off-axis objects.
