The Diver Detection Sonar ARAS 2023, developed by ARMELSAN Defense with domestic resources, has entered the inventory of the Turkish Naval Forces Command to be used on the Multi-Purpose Amphibious Assault Ship TCG Anadolu (L-400).
ARMELSAN Defense Technologies Chairman of the Board Yetkin Karakaş announced the development with the following post on his Twitter account:
"The ARAS-2023 DIVER DETECTION SONAR, which was produced for the first time in Turkey, passed the tests and entered the inventory of our Naval Forces with TCG ANADOLU. We would like to express our gratitude to SSB President İsmail Demir and SSB employees who supported us during the DTS development and production phase."
Diver Detection Sonar ARAS 2023
- ARAS 2023 is an active sonar system that can automatically detect, follow the position (distance and bearing) and classify underwater divers with open circuit breathing systems, closed circuit breathing systems or diver transportation vehicles.
- ARAS 2023, which has a 360-degree coverage, will be used to protect the Multi-Purpose Amphibious Assault Ship TCG Anadolu from underwater threats.
- Another feature of the system is that it does not require an operator. Sonar uses signal processing algorithms that distinguish a fish or a fixed object in the water from a diver, thanks to its automatic detection tracking classification unit.
- In this way, the system automatically detects and gives a warning without the need for an operator.
- Such diver detection sonars are developed by only 4 countries in the world, including Turkey.
