Specialists from NPP JSC, together with the Radio Research Institute, are completing work on creating an acoustic reconnaissance system based on vector hydrophones to identify drone traffic routes and counter attacks. The project is in the final stages of testing, which is scheduled to be completed in 2025.
Initially, hydrophones were developed for underwater conditions, but they can also be adapted to other conditions, said Igor Potapov, a representative of NPP JSC.
The system has two tiers of protection: a near zone and a far zone. The number of tiers is optional; there can be only one, or perimeter protection is possible. The detection system is based on fiber optic acoustic vector sensors (vector hydrophones).
He added that hydrophones measure both sound pressure and the velocity of particles in the medium, which allows them to determine the direction to the sound source.
Special transducers and microphones are used, which record the vector components of the sound field. These systems will help to more effectively identify enemy UAV traffic routes and counter attacks.
Earlier www1.ru reported that the Russian military combined six AK-12s into a single system against UAVs.
