Safe Alternatives to Active Sonar That Are In Use or Development by the US Navy Now
1. Passive Sonar
- IUSS (Integrated Undersea Surveillance System)
- Multi-Line Array Systems
- RPS (Robust Passive Sonar)
- A-RCI and other Advanced Signal Processing
2. Non-acoustic Sensors
- Magnetic: Silently detects temporal magnetic anomalies such as submarine hulls. Limited range.
- Satellite imaging: Satellite imaging analysis reveals submarine trails and water disturbances. Limited use.
3. Integrated Sensory Networks
