HYDROACOUSTIC COMPLEX FOR SURFACE SHIPS Russian patent published in 2023 - IPC G01S15/00 

FIELD: hydroacoustic technology.

SUBSTANCE: design of hydroacoustic complexes (HAC) for surface ships having hull-mounted (HA) and towed (TA) or lowered arrays. Essence: additional blocks are introduced, information is jointly processed from the outputs of secondary processing systems and route analysis of the receiving paths of the base and towed antennas. The joint processing system includes a block for forming a bank and identifying traces, the first output of the block for forming a bank and identifying traces is connected to a block for clarifying the parameters of jointly unaccompanied traces, connected in series with a block for checking the detection criterion for jointly unaccompanied traces, the second output of the block for forming a bank and identifying traces is connected to the block checking the criterion for tracking jointly accompanied traces, connected in series to a block for clarifying the parameters of jointly formed traces, the second input of which is connected to the output of the block for checking the criterion for detecting jointly unaccompanied traces, and the output is connected to the information input of the control and display panel.

EFFECT: expanding the functionality of the HAC for surface ships – increasing the efficiency of detecting target trajectories in difficult hydrological conditions, in particular in conditions of an intermittent structure of echo detection zones; with non-overlapping detection zones of the HAs and TAs, the time for detecting traces is reduced; with intersecting detection zones, the errors in determining the parameters of the traces are reduced and the likelihood of correct target identification increases.
