Which sonar is described as a Volume Search Sonar?

• A. Volume Search Sonar
• B. Forward Looking Sonar
• C. Side Looking Sonar
• D. Mine Detecting Sonar

Answer: (A)

Volume Search Sonar is designed to sweep a three‑dimensional region of water around the platform, providing information about objects anywhere within that volume (range, bearing, and depth). This volumetric capability is what defines a Volume Search Sonar, making it the system described by that name. Forward Looking Sonar looks ahead to detect obstacles or targets in front of the vessel; Side Looking Sonar scans to the sides, typically for seabed mapping; Mine Detecting Sonar is a general term for systems that locate mines but doesn’t inherently imply searching a volume. So the Volume Search Sonar is the best match because its core role is volumetric search, not just forward or side imagery or general mine detection.
