METHOD FOR DETERMINING THE LOCATION OF VESSELS Russian patent published in 2021 - IPC G01S15/42 

FIELD: measurements.

SUBSTANCE: invention relates to the field of measurements, navigation, monitoring and control of the movement of ships and can be used for the development of technical systems and aids to navigation, communication and management of navigation objects. The method consists in placing hydroacoustic receivers in the navigable water area, measuring the vibroacoustic effects of vessels on hydroacoustic receivers, determining the coordinates of vessels and transmitting them to vessels for navigation, while setting the frequency Δt of measurements of the amplitudes A_nj of vibroacoustic influences of the surrounding acoustic environment, the maximum time T_max measurements, frequency range of measurements, set individual vibroacoustic characteristics of vessels B_Ci, form a graphic model of the navigable water area, taking into account the terrain map, as K hydroacoustic receivers use Μ spatially distributed transducers of vibroacoustic influences, represented by fiber-optic cables, for which along the bottom of the navigable water area in the direction of movement ships lay Μ fiber optic cables, each of the Μ spatially distributed transducers of vibroacoustic influences are connected to the corresponding set of equipment Q for monitoring and recording external vibroacoustic influences.

EFFECT: increasing the accuracy and reducing the time for determining the coordinates and direction of movement of each vessel, as well as calculating the speed of movement of vessels in the water area during their navigation through the use of spatially distributed transducers of vibroacoustic effects, represented by fiber-optic cables, allowing to expand the range of low frequencies.
