echosounders technology for sustainable

es80 echosounder simrad has manufactured fishfinders for more than 70 years and has 25 years of experience using split beam technology the first split beam fishfinder a 38 khz model came on the market in 1984 quickly followed by a 70 khz model today simrad has a wide range of frequencies from 18 khz used for detecting deep water species up to 333 khz used for measuring plankton the simrad es80 is the fifth generation split beam fishfinder where the latest in computer and signal processing technology is used to satisfy the increasing need from our demanding customers “top performance at any depth and easy to perate the es80 is a wideband echosounder able to operate at a frequency range of 10-500 khz with a suitable broadband transducer the es80 can sweep chirp in a range of frequencies giving increased resolution on longer range also the es80 will have a ts response curve making it easier to determine the species you are looking at the es80 delivers unprecedented resolution on

wideband echosounders the new series of ess have wideband capabilities that means that you can transmit a signal that varies in frequency across the transmission the most common way to operate the sounder is to use linear fm or chirp in an es80 chirp transmission you utilize the effective frequency band of your transducer starting low and continuing higher until you reach the frequency where the transducer efficiency drops off suited for such environments the es80 has this capability and as the sw continues to be developed new functions would be available due to advanced matched filtering techniques you can correlate the returned signal with what you sent out and the result is improved range resolution of single targets the improved range resolution is obtained when you have targets that are in comparable size when you have very weak targets in the near vicinity of strong ones such as small fish close to bottom you might want to use a different pulse shape a dolphin’s click is

es80 details make the difference the es80 comes standard with digital cw transmission this is the transmission form that has been used since simrad as the industry first digitized the echosounder back in the mid 80’s then it is possible to add a fm transmission module to the system making the es80 a true chirp echosounder the advantage of chirp is that it is possible to transmit with a very short pulse length at very long ranges giving maximum resolution what determines a good chirp echosounder is how long range it gets on the shortest pulse in addition to this with the long experience simrad has making scientific echosounders the es80 also has a calibrated real time ts target strength curve this will give the user information about the target strength and frequency response of the return echo having a system with multiple frequencies it is now easier to determine the species you are fishing by comparing the target frequency response on different frequencies 1 the es80 has

wideband transceiver wbt the wideband transceiver wbt is designed for applications where performance is the top priority the wbt has four 500 w channels that can either work independently with single beam transducers or together with a split beam transducer the wbt transceiver is capable of operating on entire band from 10 khz to 500 khz only limited by the transducer s bandwidth the wbt is operated by the es80 sw and depending on the settings it can be used either in narrowband or wideband mode the wbt itself is capable of doing cw fm and also user defined signals about transducers in general any simrad transducer can be used with the es80 as long as it operates within the 10-500 khz band however the effective bandwidth will vary with transducers the simrad composite transducers have more bandwidth than transducers based on the tonpilz elements because of that for frequencies of 50 khz and higher we always recommend these with an es80 system es80 echosounders
