How many radars are there?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Counting radar installations is about identifying separate radar devices, not just the number of antenna elements. A radar is a distinct housing or unit, such as a dome or a panel, that operates as one radar system. In the diagram, there are two separate radar units mounted on the structure, each appearing as its own dome/panel. That makes the total number of radars two. If you ever see a single unit with multiple facing panels, that can be one radar, but here there are two distinct radars, so the count is two.
