    • Predicting underwater ambient noise with an evolutionary signal processing method 

      Alvarez, Alberto; Harrison, Chris H.; Siderius, Martin (NATO. SACLANTCEN, 2001/06)
      In this report we employ recent developments in non-linear physics and time series prediction to study the physical characteristics of measured underwater ambient sounds. Specifically, we examine the predictability of a ...

    • Prediction of rendezvous in maritime situational awareness 

      Uney, Murat; Millefiori, Leonardo; Braca, Paolo (CMRE, 2019/05)
      In this work, we consider the problem of algorithmically predicting rendezvous among vessels based on their trajectory forecasts in a maritime environment. The problem is treated as hypothesis testing on the expected value ...

    • Preliminary results of current measurements in the Strait of Sicily in May 1970 

      Molcard, Robert (NATO. SACLANTCEN, 1972/09)
      During May 1970, series of oceanographic observations were made in the Strait of Sicily in support of MILOCMED. Sections of hydrologic stations were made using temperature salinity recorder (TDS) and Nansen bottles by R/ ...

    • Principles and methods of core analysis at the SACLANT ASW Research Centre 

      Kermabon, André; Blavier, Pierre (NATO. SACLANTCEN, 1967/08)
      The methods and accuracy of measuring core parameters at the SACLANTCEN are described. Those for measuring sound velocity and electrical resistivity are explained in detail.

    • Probability of false alarm estimation in oversampled active sonar systems 

      Abraham, Douglas A. (NATO. SACLANTCEN, 1998/08)
      The probability of false alarm (Pfa)in active sonar systems is an

    • Problems of pursuit and evasion 

      Bresson, Maurice (NATO. SACLANTCEN, 1966/06)
      Problems of pursuit and evasion play significant part in naval warfare - particularly in ASW. They are of no less importance in aerial warfare and are now becoming important in space. Their practical importance has given ...
