  • Page 81: Reducing Noise And Reverberation With The Agc (Automatic Gain Control) Function

    When sonar conditions are poor, effective tuning of the filters in the ST90 may be necessary to achieve a satisfactory result. Automatic Gain Control (AGC) is one of the tools provided by the ST90 to remove noise and reverberation from the echo presentation.
  • Page 82 The AGC may misinterpret the school echo for noise. Reduce or disable the automatic gain control. The filters in the ST90 are implemented in “series”. The gain compensations are made before the AGC. For this reason, your current gain setting will always have an effect on the automatic gain control.

  • Page 83: Reducing Propeller Noise And Interference With The Noise Filter

    Use weak filtering - or turn the filter off - if you have strong echoes on short ranges. The filter may then be too powerful, and distort the echo presentation. The filters in the ST90 are implemented in “series”. The noise filtering is done in two stages early in the receiver process.

  • Page 109: Defining The Middle Position Of The Transducer

    The hull unit provided with the ST90 is designed to lower the transducer down below the ship’s hull when the ST90 shall be used. When the ST90 is switched off, the transducer is hoisted for protection. The ST90 allows you to define a middle position for the transducer.
  • Page 110 The middle position is not a fixed length. The physical middle position depends on which type of hull unit you are using with the ST90. Retracting the transducer to a middle position may be useful if you use the ST90 simultaneously with other sonars. A higher position will permit you to increase the vessel speed.

    Setting up the ST90 in a synchronized system If you want to use the ST90 as a master or slave in a synchronized system, you must set it up for such operation. To do this, you must select which communication port to use for the synchronization interface, and you must select the requested synchronization mode.
  • Page 145 • Master Master mode is used if the ST90 is going to act as the controlling unit in a synchronized system. The peripheral hydroacoustic system(s) are only permitted to transmit when enabled by the ST90. When Master mode is selected, the ST90 will run using its internal ping interval parameters and send trigger signals to the peripheral system(s).
  • Page 146 This delay will only work when the synchronization is set up using a serial port. • Slave In Slave mode, the ST90 waits for the delay time after the external trigger signal has arrived before transmitting the ping. This is often referred to as a post-trigger. From the list of ports available, select Synchronization Port This is the interface port currently used to transmit or receive synchronization signals.
