What is the primary operational advantage of towing the AN/SQR-20 Multi-Functional Towed Array below the layer where the ship's noise is carried?
What is the primary operational advantage of towing the AN/SQR-20 Multi-Functional Towed Array below the layer where the ship's noise is carried?
- It facilitates active sonar transmission with greater clarity.
- It allows for faster data processing due to reduced interference.
- It enables the array to operate in shallower waters, enhancing detection capabilities.
- It provides increased range and improved recognition differential by minimizing interference from the ship's own noise. (correct)

AN/SQR-20 Multi-Functional Towed Array
A passive/active receive-only towed array sonar system deployed behind a ship to detect narrowband and broadband frequencies at varying depths.
Study Notes
- AN/SQR-20 Multi-Functional Towed Array is a passive array towed behind a ship
- It operates passively, receiving active signals only
- It is towed below the layer where the ship's noise travels, increasing range and recognition
- It can discern both Narrowband and Broadband frequencies from contacts
- It can do so at varying depths in the water column
