In which modes does the dipping SONAR system operate?

The dipping SONAR system operates in multiple modes to effectively perform various underwater detection and tracking tasks. The correct answer encompasses a range of operational modes, including echo-ranging, passive, COMM (communication), SDC sonar (Sonar Data Computer), sonobuoy, and test mode.

Each of these modes serves a specific function:

• Echo-ranging is crucial for determining the distance to underwater objects by sending out sound waves and measuring the time it takes for the echo to return.

• Passive mode allows the system to listen for sounds made by submarines or other underwater vehicles without transmitting signals, which aids in stealthy operations.

• COMM mode refers to communication functionalities that the system can use to transmit and receive data.

• SDC sonar provides advanced data processing and display capabilities for sonar signals.

• Sonobuoy mode utilizes small, buoyant devices that are dropped into the water to listen for sounds, typically used in anti-submarine warfare.

• Test mode is utilized for system diagnostics and calibration to ensure proper functionality before deployment.

This comprehensive functionality is vital for modern naval operations, particularly in anti-submarine warfare, where effective detection and classification of underwater threats are essential for mission success.
