Wideband low frequency transducers are crucial enablers for building underwater communication networks. The use of low frequencies promises long range communication ranges, but most low-frequency transducers are large, lack directionality and have li

Due to the proliferation of submarines and the improvements in torpedo technology (endurance, intelligence), naval surface vessels experience an ever increasing torpedo threat level. To counter this threat, torpedo defence systems have been developed

Sound-recording acoustic tags attached to marine animals are commonly used in behavioural studies. Measuring ambient noise is of interest to efforts to understand responses of marine mammals to anthropogenic underwater sound, or to assess their commu

This paper is dedicated to the work of Pieter Schippers and gives an overview of his achievement in sonar performance modelling over his career. This publication is the last of a long list, many of which published at UDT [1-5]. A historical review is

Continuous Active Sonar (CAS) is an emerging technology in anti-submarine warfare operations. The feasibility of the technology has been demonstrated and it has been shown that CAS has a potential to reduce false alarm rates in reverberation-limited

Several navies are operating or procuring low-frequency active sonar systems (LFAS) as the primary part of their ASW capability. Since LFAS is a relatively new sensor with a performance strongly depending on environmental conditions, the proper opera

Existing sonar systems are commonly deployed at a low duty cycle, i.e. a short transmit signal is used followed by a long listening time. As a result, the target is only illuminated during a short time resulting in only one detection opportunity per

Existing surveillance sonar systems for anti-submarine warfare (ASW) use a pulsed sonar deployed at a low duty cycle. Continuously active sonar (CAS) is of special interest since the technique could provide better detection performance than conventio
