ANTENNA MODULE Russian patent published in 2020 - IPC G01S7/52 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to hydroacoustic equipment and can be used in development and manufacture of ship receiving hydroacoustic antennae placed on submarines, surface ships and underwater vehicles. Technical result is achieved by simultaneous application of three technical solutions: 1) installation in each hydroacoustic receiver (HAR) along axis of their symmetry of shock-absorbing devices in the form of polymer rods, which allows reducing frequency of natural oscillations of HAR as compared to antenna module (AM) vibration oscillations; 2) by mismatch of at least twice frequency of intrinsic oscillations of HAR included in composition of AM, which is achieved by using polymer rods with different stiffness coefficient; 3) arrangement of all HAR, which are part of AM, in tight shell filled with vibration-absorbing polymer material, which provides additional damping of oscillations of receivers.

EFFECT: high vibration resistance of HAR included in the AM.
