Which term is listed as a radar topic that relates to dividing the radar coverage into zones?

• A. SPOKING
• B. Hourglass Effect
• C. SECTORING
• D. Echo Averaging

Answer: (C)

Dividing radar coverage into zones is sectoring. Sectoring breaks the radar’s azimuth field into multiple angular sectors around the antenna, so each sector can be scanned or processed with its own settings. This allows you to tailor scanning rates, thresholds, and display priorities for different parts of the coverage area, helping maintain effective surveillance and target detection across a wide field while focusing resources where needed. The other terms don’t describe creating distinct zones: spoking isn’t about partitioning coverage, the hourglass effect refers to a pattern that can arise from certain scanning geometries rather than intentional zoning, and echo averaging is a signal-processing method to boost detectability rather than divide the view into zones.
