    • Adaptive filter of seabed clutter onboard the AUVs of an active multistatic sonar network 

      Micheli, Michele; Tesei, Alessandra; Ferri, Gabriele; Stinco, Pietro (CMRE, 2019/05)
      This work aims at reducing the false alarm rate of a multistatic active sonar working in coastal, shallow waters. The sonar system is implemented through a heterogeneous manned-unmanned network including autonomous underwater ...

    • Adaptive underwater sonar surveys in the presence of strong currents 

      Williams, David P.; Baralli, Francesco; Micheli, Michele; Vasoli, Simone (CMRE, 2017/11)
      We consider the task of conducting underwater surveys with a sonar-equipped autonomous underwater vehicle (AUV) in environments with strong currents. More specifically, this topic is addressed in the context of mine ...

    • Autonomous networked anti-submarine warfare research and development at CMRE 

      LePage, Kevin D.; Goldhahn, Ryan A.; Alves, João; Strode, Christopher; Braca, Paolo; Ferri, Gabriele; Munafò, Andrea; Oddone, Manlio; Sildam, Jüri; Baralli, Francesco; Biagini, Stefano; Canepa, Gaetano; Colombo, Marco; Grandi, Vittorio; Grenon, Gabriel; Mazzi, Marco; Micheli, Michele; Parisi, Gerardo; Saia, Paolo; Vermeij, Arjan; Zappa, Giovanni (CMRE, 2019/06)
      CMRE has been evaluating the potential of autonomous networked ASW using underwater vehicles through a program of sonar signal processing, underwater communications, navigation and robotic behavior developments and at-sea ...

    • Forward looking sonar mosaicing for mine countermeasures 

      Ferreira, Fausto; Djapic, Vladimir; Micheli, Michele; Caccia, Massimo (CMRE, 2019/06)
      Forward looking sonars (FLS) are nowadays popular for many different applications. In particular, they can be used for Automatic Target Recognition (ATR) in the context of Mine Countermeasures. Currently, ATR techniques ...

    • In-situ acoustic received level measurements with glider based reactive behaviour 

      Jiang, Yong-Min; Alvarez, Alberto; Cecchi, Daniele; Garau, Bartolome; Micheli, Michele (CMRE, 2019/06)
      Buoyancy-driven underwater gliders are typically employed to sample the water column environment in the ocean [1]. As one of the efforts of extending the capabilities of traditional underwater gliders, CMRE has been working ...

    • Multi-waveform active sonar tracking 

      Coraluppi, Stefano; Carthel, Craig; Hughes, David; Baldacci, Alberto; Micheli, Michele (NURC, 2007/06)
      This paper extends the NURC distributed multihypothesis

    • On-board real-time assessment of acoustic environmental parameters relevant to the estimation of sonar performance for autonomous underwater vehicles 

      LePage, Kevin D.; Oddone, Manlio; Micheli, Michele; Strode, Christopher; Tesei, Alessandra (CMRE, 2019/05)
      CMRE is evaluating the use of autonomous robots for the detection and tracking of underwater targets. Robotic detection and localization comes with many challenges, not the least of which is the requirement to maximize the ...

    • Real-time continuous active sonar processing 

      Canepa, Gaetano; Munafò, Andrea; Murphy, Brian; Micheli, Michele; Morlando, Luca (CMRE, 2019/06)
      This work describes the development of continuous active sonar (CAS) processing at CMRE. The software uses subband processing to achieve a faster update rate than is possible with pulsed active sonar (PAS). The software ...

    • Real-time underwater positioning and navigation of an AUV in deep waters 

      Tesei, Alessandra; Micheli, Michele; Vermeij, Arjan; Ferri, Gabriele; Mazzi, Marco; Grenon, Gabriel; Morlando, Luca; Biagini, Stefano; LePage, Kevin D.; Costanzi, Riccardo; Fenucci, Davide; Caiti, Andrea; Munafò, Andrea (CMRE, 2019/05)
      Due to the absence of GPS, navigation of autonomous vehicles underwater requires the integration of various measurements to provide the best location estimate. Usually in littoral waters, adequate navigational accuracy may ...

    • Scalable adaptive multitarget tracking using multiple sensors 

      Meyer, Florian; Braca, Paolo; Hlawatsch, Franz; Micheli, Michele; LePage, Kevin D. (CMRE, 2019/06)
      In networked mobile multitarget tracking systems, parameters such as detection probabilities, clutter rates, and motion model parameters are often unknown and time-varying. Such parameter variability can seriously degrade ...
