What shape is the radio wave energy transmitted by police traffic RADAR concentrated into?

The concentration of radio wave energy in police traffic RADAR is typically shaped like a cone. This conical shape allows the RADAR system to effectively focus its energy in a specific direction, facilitating the detection of moving vehicles within that area. When the RADAR beam is emitted, it spreads out as it travels, creating a cone that is wider at greater distances. This configuration is advantageous for measuring speed and analyzing traffic patterns, as it enables the RADAR to cover a wider area while still maintaining a focus on the target. The design essentially maximizes the RADAR's ability to detect and track objects, making the conical shape optimal for traffic enforcement purposes.
