Performance assessment of broadband impulsive noise jammers
(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 ...
Mutual coherence and silence
(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 ...
