The present chapter is about coastal border control for threats entering the coastal waters under the water surface. This threat consists mainly of covertly operating submarines. Acoustic sensors are commonly used for the detection of these submarines, as illustrated by the recent (renewed) deployment …

This book provides a comprehensive study of border control: from data analysis and information warfare, frameworks for command and control, and game-theoretic risk management, up to the (optimal) deployment of law enforcement missions. Innovative about this book is that it approaches the subject from …

This paper discusses the principle of geoacoustic inversion. That will demonstrate the need for validation with experimental data. The RNLNC has been involved in two recent sea trials that will be described in brief. Results for the geoacoustic parameter characterization for typical examples will be …

The author investigates how acoustic information about the seabed can be obtained from bottom-reflected shipping noise. An innovative idea is the use of sound sources of opportunity. When expeditionary forces enter shallow or confined waters, the environment has a great influence on the performance of …
