How many search modes are there?

• A. 4
• B. 5
• C. 3
• D. 6

Answer: (B)

Search modes are different scanning patterns the radar can run to cover airspace, each with its own coverage and update rate. There are five such modes, giving operators the ability to switch between broad situational awareness and focused tracking as threats appear. This setup balances detection probability across ranges, elevations, and target speeds, so five is the number described in the material. Using fewer modes would limit coverage or responsiveness, while more would add unnecessary complexity. In practice, you’d pick a mode based on whether you need wide-area surveillance or rapid reacquisition on a target.
