Abstract: A support structure of hydrophones for a towed array sonar system includes elastic members arranged in each sensor package and adapted to support a hydrophone received in the sensor package while attenuating vibrations transmitted to the sensor package. External vibrations, such as vibrations generated due to the running of a towing vessel or vibrations induced due to motions of a towing cable, which are irrespective of acoustic waves reflected by a target moving underwater, are attenuated by the hydrophone support structure during the transmission thereof from the sensor package to the hydrophones, so that the hydrophones are suppressed from vibrating due to the external vibrations. Accordingly, it is possible to reduce noise included in output signals of the hydrophones, thereby achieving an improvement in the sensing performance of the towed array sonar system.
