New : MATISSE-v3.6 is available !

The radiative transfer code MATISSE can help to design/realize optronic sensor and develop detection algorithm in spectral bandwidth ranging from 0.25 (LOS) / 0.4 (IMG) to 14 μm. It provides:

• spectral images of natural backgrounds as clear atmosphere, water and ice altitude clouds, geolocated land and sea, as seen by spaceborne, airborne or shipborne sensors.
• path transmission and radiances along a line of sight, with special care of mirage effect at very low altitude above sea surface
• contribution to the evaluation of target / background contrast (line by line) 
• sky radiance or local illumination around a target point for signature computation.
• turbulence characterization for VIS, IR imaging

>> MATISSE-v3.6 infrared image as seen by a spaceborne radiometer (at 4.0 µm in clear sky condition)

>> MATISSE-v3.5 infrared (3-5 µm) sea surface image at grazing angles

>> MATISSE-v3.5 use of very low altitude above sea surface propagation model
(Spectral path radiance and transmission with extremity zenith angles computation)

MATISSE manages a whole collection of global geolocated and complementary databases: atmospheric profiles, aerosols, digital terrain elevation and biome, cloud’s optical parameters, ground spectral reflectivity… Databases consistence is provided. A graphical user interface (GUI) helps to define your computational cases.

MATISSE represents about fifteen years of studies and development with gathers part of modeling done at Onera and in collaboration with research laboratories (IREENA, IRIT, LMD, LOA, Météo-France/CNRM, RDDC…). Validation is included in MATISSE development by periodic comparisons with measurements (example: MIRAMER field campaign for the sea surface model).

The code was used by DGA (French MoD), French Defense companies and research laboratories.

MATISSE-v3.6 reference version is available under French MoD supervision (license agreement acceptance needed).
