Pie in the sky ideas here... but how far is active sonar effective for? Can you launch a probe that enables active sonar some 50-100 miles away, and radios the results back? Or would the depth prevent any type of radio communication...or is active sonar not that long-range?
This whole field is really fascinating to think about.
- nradov 5y agoThe effective range of active sonar varies tremendously based on many factors: power output, microphone sensitivity, signal processing, bottom contour, water temperature, ambient noise, etc. There is no typical range. Aircraft can drop active sonobuoys but they're very expensive and in limited supply. Use of active sonar is restricted in many areas due to impact on marine life. Water blocks all radio traffic except for extremely low frequency. The bandwidth on that is too low to use as an effective navigation aid, and transmissions can only be sent from large facilities on land. Some submarines can also send up floating antennas on towed buoys but they prefer not to do so due to the risks of detection and entanglement.
