Ship sonar SN50

multibeamelectronichigh-resolution

The Simrad SN50 is a high-resolution matrix sonar. Depending on your installation choice, you can use the SN50 system as a multibeam echo sounder, a seine sonar, a trawling sonar, or a navigation aid. Unlike an Omni sonar, a matrix sonar uses a fixed, square transducer with the elements placed in a rectangular matrix pattern. The advantage is a focused coverage area in the direction the transducer face. If you install the transducer facing straight down, the sonar system will perform as a multibeam echo sounder. With the transducer facing horizontally to the port or starboard side, the SN50 system works as the seine sonar, looking into the purse seine. If you install the transducer facing forward, you can use the sonar system for trawling or navigation. Key specifications All transceiver electronics are placed inside the transducer. This means fewer cables, less noise and easier installation. The centre operational frequency is 57 kHz. You can select any operational frequency from 55 to 59 kHz. This frequency range gives you an operating range of up to 2500 metres depending on the acoustic conditions. The transducer is fitted with 144 transducer elements in a matrix array. A dedicated mounting house has been developed to make installation easier. The transmitted sonar beams can be tilted electronically. This allows you to search the whole water column and optimise the sonar performance to match the acoustic conditions. A built-in stabilizing system is included for electronic pitch and roll compensation, but you can connect to an external sensor for improved accuracy.
