Optical characteristics of small surface targets, measured in the False Bay, South Africa; June 2007

During the False Bay trial (June 2007), the performance of a set of three optical sensors was tested against several small surface targets in a coastal area: a hyperspectral camera, a camera with a rotating polarization filter and a high resolution camera. One objective was the validation of a contrast and clutter model for the visual spectral...

Overview of maritime situational awareness research at the Netherlands Organization for Applied Scientific Research TNO

This paper gives an overview of research at TNO in the field of maritime situational awareness (MSA). Our expertise on radar, sonar, electro-optics, electronic support measures and tracking/fusion is typically employed for vessel detection and vessel anomaly detection. Illustrative examples of these applications are presented addressing the...

Wireless sensor networks in a maritime environment.

In the recent years, there has been a lot of research on sensor networks-and their applications. In particular for monitoring large and potentially hostile areas these networks have proven to be very useful. The technique of land-based sensor networks can be extrapolated to sensing buoys at sea or in harbors. This is a novel and intriguing...

Satellite and Ship-based Lidar Measurements of Optical Depth during EOPACE

Knowledge of the coastal MABL for the entire battlespace is critical for modern Navy operations. To support modern weapon and sensor systems, quantitative assessment of a number of MABL properties are needed. They include: optical depth, boundary layer depth, sea surface temperature, and surface layer temperature and moisture. These needs are...

Small Surface Target Detection with EO/IR Sensors

The detection of small surface targets at sea is an increasing requirement for warships. The present sensors on board do not provide the required detection probabilities for these low observable targets like small rubber boats, floating mines, periscopes, people etc. The reason for the low probability of detection is not only the low contrast...

Satellite and Ship-based Lidar Estimates of Optical Depth during EOPACE

Coastal Marine Atmospheric Boundary Layer (MABL) aerosol optical depth is estimated from satellite data and compared with ship-based aerosol and lidar backscatter measurements, aircraft-measured aerosol, and rawinsonde data during the EO Propagation Assessment in Coastal Environments (EOPACE) Intense Observing Period (IOP) during April 1996. In...

Maritime Infrared Background Clutter

The detection of small targets in maritime infrared surveillance is hampered by the presence of clutter. Sea surface structure, reflection and emission changes related to incident angle variations and surface effects are standard features governing the clutter behavior. Also special effects as sun glint an horizon effects play an important role...
