Recent Developments in SOBEK Passive Sonar Technology

2012
Surveillance of waterside locations for protection against threats from small fast surface vessels and underwater intruders is a very relevant but challenging problem. For this reason, the Netherlands Organisation for Applied Scientific Research (TNO) is developing SOBEK – a family of passive sonar technologies for waterside surveillance.

Improving Protection Agains Intruders Using Passive Sonar [PDF]

, 2011
Divers and small vessels are increasingly recognized as a potential threat to high value assets. Harbour and waterside surveillance systems that are used to counter the threat of divers are usually based on active sonar, whose performance can be limited by reverberation in a harbour environment.Passive techniques are based on the detection of the sound

Optimization of Conventional Passive Sonar Detection Systems

1969
Abstract : The report examines three methods for maximizing the output signal- to-noise ratio of a conventional passive detection system consisting of a fixed array, non-adaptive beam forming, and square-law detection. The performance of a non-optimal system is compared to each of the three optimum configurations, and the results suggest how an ...

Direction of Arrival Estimation in Passive Sonar

2012
Since World War I, the area of acoustic undersea warfare has witnessed several research activities targeting the development of advanced systems to accurately detect and localize underwater moving targets. One of the main categories of these systems is the passive sound navigation and ranging (SONAR) that searches for the location of the ships and ...
