Abstract: This paper proposes a new 2D direction finding algorithm using vector hydrophone array. A vector hydrophone comprises of two or three velocity hydrophones plus an optional pressure ...

Abstract: Passive target motion analysis (TMA) of an underwater or surface object relies on bearing only measurements captured by hydrophone sensor-array, which is being towed by an own-ship. These ...

Omnitech provides advanced sensor systems for underwater surveillance, acoustic and electromagnetic ship-signature measurements and mine clearance diver training. Products include: low-power ...

The systems use flat multi-channel hydrophone arrays to generate high resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers and provides excellent penetration in various bottom ...

Diode arrays, such as a SIP diode array, are a single inline or system packaged diode array. The objective of SIP diode arrays is to merge many electronic requirements of a functional system or a ...

signal sensing capability that leverage signal phase along with the drone's motion to emulate an "antenna array in air" for ...
