AQUA stationary hydroacoustic system
The “AQUA” stationary hydroacoustic system for detecting underwater and surface objects is a series of linear phased array antennas (PAR) installed on the seabed, consisting of receiving elements (hydrophones) that can be carried out at a distance of tens to hundreds of kilometers from the coastline. Detection of underwater objects in the active vertical sonar mode at the border of the protected area of ??the water area. Detection, classification and tracking of underwater and surface objects in noise detection mode.
The system consists of a remote (underwater) part and surface equipment of the observation point. The remote part of the system provides radiation and reception of a sounding signal, primary processing of signal information, information transfer to a stationary surface observation point in the form of a form of a detected target.
