[. . . ] In case of voltage failure, the transducer can be raised or lowered manually by means of a hand crank. The sensor for the electronic stabilisation of the sonar beams is housed in the Motor Control Unit, which is mounted on the Hull Unit. Transducer The cylindrical Transducer allows the sonar beam to give full 360 degrees coverage of the water volume down to -60 degrees. 8 337432/A Simrad HOS 152 System diagram Figure 3 HOS 152 Simplified system diagram HOS 152 items A B C D E F G H Processor Unit Beamformer Unit Colour Monitor Operating panel Transceiver Unit Motor Control Unit (mounted on the hull unit) Hull Unit Transducer (mounted on the hull unit) 337432/A 9 Simrad HOS 152 Basic functionality The basic principles of the Simrad HOS 152 are unique because of the 256 separate transmitter and receiver channels with their transducer elements spread around on the cylindrical transducer. The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware. Omni beam When the Omni beam is tilted, the total beam picture can be compared with folding an umbrella, which means that all beams in 360 degrees around the vessel have the same tilt angle. Figure 4 Omni beam principle The beam can be tilted from +10 up to -60 degrees down. In addition to seeing the target from above, it is also possible to see the target from the side, by using the vertical slice presentation. In this case the beam covers a continuous vertical beam from 0 to -60 degrees in one transmission. 10 337432/A Simrad HOS 152 Figure 5 60 degrees vertical slice This vertical slice, which is presented by the white audio line in the horizontal picture, can be selected to any bearing by the manual training control. The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation. The AGC will thus provide automatic scaling of the data in order to maintain proper dynamic range based on all echo values The strength of the filter can be selected in the menu. RCG (Reverberation Controlled Gain) The RCG function adjust the picture to minimize influence from bottom and surface reverberation. The strength of the filter can be selected in the menu. With maximum strength is selected, the RCG will effectively reduce the bottom in shallow water, while variations on the bottom will be displayed. Note that scattered fish can be perceived as reverberation. To close a parameter dialog, click the Close button. Most dialogs provide a Help button for access to the on-line help. In this example you can see the Status dialog, which is replaced when a parameter dialog is opened. (CD015009A) 337432/A 15 Simrad HOS 152 OPERATING PANEL The most frequently used functions are directly accessible by the designated control buttons on the Operating Panel, and may enter operational commands directly. The buttons are grouped in fields according to their purpose. Most sonar functions are also accessible and activated using the menu system on the display and the trackball and Select button on the Operating Panel. Figure 9 Operating panel A B C D E F G H I Main switch: Power the sonar on (and off), lower the transducer Symbol: Control the target markers providing exact latitude and longitude positioning. Mode: Select your favourite display mode or user setting with the push on a button. Gain: Separate gain control for vertical and horizontal sonar presentation. Range: Separate range control for vertical and horizontal sonar presentation. Cursor: Menu and cursor control. Tilt: Easy control of the sonar's tilt angle, or start automatic search program. Various: Store interesting screen captures, and zoom in on details. Train: Manual control of beam training, start automatic search and tracking programs. 16 337432/A Examples EXAMPLES This page presents several screen captures taken from actual operations on fishing vessels. Figure 10 Herring On this screen capture, you can see that the sonar has detected three schools of herring. The skipper has decided to catch the school with highest density, and this is the school closest to the vessel. The sonar is in Automatic Target Tracking mode, and shows the tracks from the school and vessel. In the lower left corner you can see the course, depth and speed of the school; 179 degrees, 350 meters depth and 2, 2 knots. [. . . ] The drawing is not in scale.
