Abstract
This document is the user guide for a demonstration tool developed in Matlab to compute radiometrically accurate synthetic scenes and in-pixel statistics. The tool is tailored principally towards maritime applications since atmospheric and aerosol models used are designed for calculations over a large body of water. Furthermore, the lower surface used for radiance calculations as well as pixel statistics is by default based on the DRDC sea surface BRDF (Bidirectionnal Reflectance Distribution Function) model [1][2][3], although a Lambert surface can also be used. The first objective of the tool is to demonstrate how SMARTI (Suite for Multiresolution Atmospheric Transfer Interface) [4] can be used for fast, physics-based simulations of background images as measured by wideband optical or infrared cameras. The second objective is to demonstrate the calculation of sea surface clutter statistics using the model developed at DRDC [5]. Once configured, the tool is designed to lead the user through different calculation steps. These include: 1) Definition of atmospheric and radiative transfer parameters; 2) Definition of surface properties; 3) Visualization of atmospheric characteristics; 4) Definition of scene and sensor parameters; and 5) Visualization of results. Configuration, as well as all of the steps mentioned above are described in the following sections.
