Results from the search-lidar demonstrator project for detection of small Sea-Surface targets

Coastal surveillance and naval operations in the littoral both have to deal with the threat of small sea-surface targets. These targets have a low radar cross-section and a low velocity that makes them hard to detect by radar. Typical threats include jet skis, FIAC's, and speedboats. Previous lidar measurements at the coast of the Netherlands...

IRST Infrared Background analysis of Bay environments

Present-day naval operations take place in coastal environments as well as narrow straits all over the world. Coastal environments around the world are exhibiting a number of threats to naval forces. In particular a large number of asymmetric threats can be present in environments with cluttered backgrounds as well as rapidly varying atmospheric...

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...

Multispectral maritime background and clutter effects on small surface target detection

This paper concerns multispectral backgrounds and clutter as they hamper the detection process of small surface targets. The variability of target contrast is shown for a number of meteorological conditions in the various spectral bands, for which new types of sensors have become available. It is shown that simultaneous framing with pixel co...
