Advanced Training:

SiPLAB is willing to host PhD or postdoc candidates to pursue their training as well as scientists wishing to do their research in SiPLAB's field of interest (see below) or other connecting areas.
Prospective candidates/scientists must have a sound background in
  • Physics
  • Electrical Engineering
  • Computer Science
  • Applied Mathematics
PhD candidates may have enrolled in PhD programs at University of Algarve (UALG) or in other Universities in Portugal or abroad. In any case SiPLAB, as hosting institution, will comply with regulations and deadlines of specific doctoral programs or, if required, will take the necessary steps towards the completion of a joint program to the specific HIE awarding the degree, in Portugal or abroad.

vector sensor processing

Array signal processing

Since 1992, SiPLAB has been producing state of the art work in the area of array signal processing applied to underwater acoustics with over 100 publications in the subject. Moreover this work has been supported in world class experiments at sea and the development of sea-going equipment. Most of this work has been made thanks to a large group of PhD students and postdocs recruited worldwide and has led to a consequent number of dissertations that have been publicaly defended at the University of Algarve and in other universities of the highest quality.

Marine Technology

One of the strongest aspects of the work being developed at SiPLAB during the last years is a significant component on specific hardware development. This work has included the development of research prototype that allow for at sea deployment and testing of innovative features resulting from theoretical research.

Featured products:

Logo of project JONAS


download zip or github, a Python open source version of the PAMGuide package for Passive Acoustic Monitoring that features the Exchange Data Format (EDF) for facilitated underwater acoustic data sharing and metadata handling. Python allows for a crossplatform licence free processing of raw acoustic data and EDF output. A library of Python routines for EDF data reading and writing are also available. See manual here.

Head wave propagation using Traceo


an efficient Gaussian beam 2D ray tracing model for underwater acoustic propagation, handling full bottom and water column range dependency, obstacle scattering and producing particle velocity outputs. See manual here and download a free copy for Fortran. A C version for linux and/or Windows is available here and for GPU here.
