The Concept of Creating Mobile Means for Detecting Low-Noise Underwater Sources Using Vector-Scalar Antennas Transported by a Group of AUV

The report proposes a new concept for the creation of robotic mobile complexes for detecting low-noise underwater targets as a new generation of underwater environment illumination equipment. An important element of the concept is the formation and use of a vector-scalar antenna to increase the detection range in comparison with single vector-scalar receivers (VSP). When implementing new data processing algorithms, this provides a significant increase in the accuracy of the angular resolution for the search object. The proposed new concept of constructing a robotic underwater environment illumination system is based on holographic frequency-space-time processing of received sonar signals. The holographic method of localization for low-noise sources is implemented by a two-dimensional Fourier transform of the interference pattern formed by a moving source. The key factor of the concept is the placement of a receiving antenna with VSR and processing facilities on board an autonomous underwater vehicle capable of operating additionally in the underwater glider mode due to the presence of buoyancy control systems on board. The model of application for the described robotic complex for solving detection problems is given. Future plans for the full implementation of the proposed concept are considered.
