DRASS Seminar

DRASS Seminar

Following the invitation from the University of Pisa at the last DII Talks (Dipartimento di Ingegneria dell’Informazione), attended by the entire second-year Telecommunication Engineering postgraduate course, DRASS held a seminar in which its main activities were introduced, its two fields of development: Commercial Diving and Defence. The conference had a particular focus on technology applied for exterior communications and sonar processing on submarines.
The general architecture and typical communication standards of exterior communication systems in civil and military field was described, including GMDSS system (Global Maritime Safety System), ALE3G (Automatic Link Establishment) and the use of SDR (Software-defined Radio) for military communication.
In addition, the sonar processing architecture and its functionality of detection, tracking and analysis of tracks was discussed, going into detail on the techniques such as DEMON (Demodulation of Envelope Modulation On Noise) and LOFAR (Low-Frequency Analysis and Recording).
In conclusion, DRASS gave an overview of the interaction between the sonar system and other systems in submarines such as CMS (Combat Management System) and WECDIS (Warship Electronic Chart Display & Information System).
