Abstract
Sonars developed in Tallinn Technical University use complex structure-probing signals that allow effective measurements to be made with significantly lower power emissions and consumption. In current implementations, feature detection is possible up to a distance of 170 m using a transmitter with emissions of 5 W, and up to a distance of 300 m with emissions of 30 W. Lower power emissions, aside from saving energy, reduce environmental damage, and can remain practically undetected. This sonar is designed as a device/module that allows the construction of sonar systems varying in size and purpose — it has been used for bathymetry surveys. In addition to several multichannel and multi-beam sonar systems, experimental sidescan and subbottom sonar systems have also been developed.
