Saberi, A.K. (author), Vissers, J. (author), Benders, F.P.A. (author)Initiatives such as smart mobility and automated driving bring new concerns such as safety and security for the automotive industry. New architecture and designs are required for the in-vehicle systems to address these emerging concerns. Early design decisions have a large impact on the required functionalities as well as the quality attributes...conference paper 2019

Benders, F.P.A. (author), Colin, M.E.G.D. (author), Schippers, P. (author), van Vossen, R. (author)Accurate knowledge on sonar performance is critical for design and deployment of any type of sonar. The assessment of sonar performance, however, is a complex task since it depends on system parameters and settings, target properties and tactics and on the environmental conditions. TNO has accumulated more than 30 years of sonar performance...conference paper 2012

(author), TNO Defensie en Veiligheid (author)More than a decade ago, the long-term NATO scientific study “Maritime Operations in 2015” (MO 2015) identified the so-called multi-platform and co-operative multi-static Low Frequency Active Sonar (LFAS) concept, involving co-operative sonar data exchange between surface ships and submarines. Several studies have since shown the benefits of...conference paper 2009

(author)Acoustic underwater communication is essential for the participation of friendly submersible vehicles in netcentric operations. To prevent interception of exchanged information and, not less important, detection of the submersibles in a hostile environment, the communication should be sufficiently ‘covert’.
