    • Mutual coherence and silence 

      Debart, Hubert P. (NATO. SACLANTCEN, 1985/01)
      In this paper we are developing the theoretical principle of a modification of the acoustical emission by a ship. Its objective is making inefficient the angular measurements achieved by a detector. More precisely, the ...

    • Performance assessment of broadband impulsive noise jammers 

      Heine, J.; Theriault, Kenneth B.; Boseck, D. (NATO. SACLANTCEN, 1993/08)
      A noise jammer raises the noise level observed by a threat sonar to degrade the sonar's detection performance. In this paper we assess the potential for a specific noise jammer waveform used to countermeasure low frequency ...
