Equivalent beam angles for several standard transducers
Original version
This report is not to be cited without prior reference to the authorAbstract
Nominal values for the equivalent beam angle are given for several
transducers. These are the standard split-beam transducers designed for the
SIMRAD EK500 scientific echo sounder, with operating frequencies of 38 and
120 kHz, and the new two-beamwidth SIMRAD ESS transducer, with operating
frequency of 38 kHz.
