Which statement describes an Active ESA?

Which statement describes an Active ESA?

• A. Single-track, multi-transceiver
• B. Stealth, multi-track, partial fxn
• C. Non-stealth, fixed beams
• D. Passive only

Answer: (B)

Active electronic surveillance assets transmit signals to gather information rather than just listen, so they are designed to operate with some degree of stealth to avoid giving away their presence. They can monitor multiple targets at once, using several sensing channels or processing streams, which is the multi-track capability. At times, a system may not have all features fully up and running, leading to partial functionality. This combination—stealth operation, the ability to track multiple targets, and only partial functionality—best describes an Active ESA. The other descriptions either emphasize non-stealth operation, fixed beam structures, or purely passive behavior, which don’t align with the active, multi-target, stealth characteristics.
