The FATMOSE trial (False Bay Atmospheric Experiment) is a continuation of the cooperative work between TNO and IMT on atmospheric propagation and point target detection and identification in a maritime environment (South Africa). The atmospheric transmission, being of major importance for target detection, was measured with the MSRT multiband...

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...

The impact of atmospheric turbulence in the marine boundary layer on the performance of ship-borne and coastal optical and infrared surveillance sensors is well known. On the one hand, the detection process may benefit from scintillation of signals from point-like targets at long range, while target identification is hampered by turbulence...

Complementary to a measurement campaign of small surface targets in the False Bay, South Africa [1], a set-up could be arranged of atmospheric propagation experiments. This opportunity allowed us to collect another set of transmission data in a coastal area, where the environmental conditions are generally non-homogeneous and rapidly changing....

The knowledge of the atmospheric aerosol characteristics is of great importance for the range performance of Infrared and Electro-Optical sensor systems. The composition, the concentration and the size distribution of aerosols determine their scattering behavior as function of wavelength and thus their attenuation of light beams. When studies...

Optical refraction tends to occur frequently in the atmospheric boundary layer. Due to a gradient in the temperature as function of height, rays are bending down towards the earth (super-refraction), or up towards to the sky (sub-refraction). As a consequence, images of targets at long range may be distorted and mirages may occur, while the...

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...

The atmospheric conditions in the Persian Gulf region are significantly different from other places in the world. The particle size distribution may vary daily and during the day. The aerosols can contribute to the amount of rainfall over land, important for the nations around the Gulf. In 2004 NASA/GSFC and NRL (Naval Research Laboratory)...

The successful demonstration of the LOTUS landmine detection system was discussed. The demonstration of the integrated multi-sensor mine-detection system took place in August 2002 near the village of Vidovice, in the northeast of Bosnia and Herzegovina. The system consisted of a metal detector (MD) array, an infrared (IR) camera system and a...

Following scintillation experiments during EOPACE measurement campaigns in the spring of 1996, a new set of experiments was designed in November 1996 and August/September 1997 over San Diego Bay. The main purpose was to further investigate the discrepancy between measured scintillation data and values predicted from turbulence models. One simple...

A model was developed for the prediction of turbulence in the marine surface layer. The model requires standard meteorological values of air temperature, air humidity, wind speed each from any given height from within the surface layer and the sea surface temperature. Internally, the model is controlled by the exchange coefficients for momentum,...
