Which capability is described for AESA?

Which capability is described for AESA?

• A. Provides air-to-air and air-to-ground modes for target detection
• B. Only air-to-air detection
• C. Ground mapping only
• D. Passive reception only

Answer: (A)

AESA radars are multi-mode, actively scanned systems that can search and track targets in both air and ground domains. The key idea is that this type of radar uses many transmit/receive modules to steer beams electronically, so it can rapidly switch between modes and handle multiple targets. That capability lets it perform air-to-air detection for enemy aircraft as well as air-to-ground detection for ground targets, including functions like ground mapping. So the description matches the dual capability: operating in both air-to-air and air-to-ground modes for target detection. The other options are narrower or describe passive sensing, which AESA is not.
