What does ADAR stand for?

The term ADAR stands for "Air Deployable Active Receiver Sonobuoy." This designation is used to identify a specific type of sonobuoy that can be deployed by aircraft and is designed for detecting underwater objects, particularly submarines. It emphasizes the deployment method, indicating that the sonobuoy is intended for use from the air, enhancing the effectiveness and range of maritime surveillance and anti-submarine warfare operations.

Understanding the specific functions and capabilities implied in the name helps clarify its role in naval operations. The "Active Receiver" part of the name indicates that the sonobuoy actively listens for and processes acoustic signals, allowing it to detect and identify submarine activity more effectively.

The other options reflect variations in the terminology but do not accurately define ADAR in the context of naval warfare and technology. For example, "Airborne" and "Automated" denote different aspects that are not relevant to the specific function of this sonobuoy designation. The "Advanced" version also does not align with the established terminology typically used in the Navy's classification of such equipment.
