An exhaust plume trajectory and IR emission model predicts the infrared signature of diesel engine and gas turbine exhaust systems. Optical surface properties are measured, analysed and input following the methods of Vaitekunas et al. As shown in Figure 2, a platform model is constructed from an AutoCAD™ 3DFace (.DXF) or Pointwise™ T-Grid (.msh) file, forming the geometric basis of both a radiative heat transfer and in-band surface radiance model which includes diffuse and specular multi-bounce reflections. A proprietary sea reflectance model computes both the average and RMS variance in sea radiance using the methods of Mermelstein (1994) and results from both Shaw and Churnside (1997), and Ross and Dion (2007). Basic sensor information, geography, and meteorology (including date and time) are input to the background model utilizing MODTRAN for sun and sky radiance, and atmospheric propagation. The ShipIR components shown in Figure 1 consist of an observer, background, and platform. ShipIRINTCS is a comprehensive software engineering tool for predicting the thermal infrared (IR) signature and IR susceptibility of naval warships. A sequence of scenarios are used to test and demonstrate the new flare model during a missile Which prevented reliable tracks from the adaptive track gate algorithm already presented by Ramaswamy and The new model also eliminated artifacts and deficiencies in our previous model A sensitivity analysis on each input parameter provides the data and methods needed to synthesizeĪ model from an IR measurement of a decoy. Modelled stochastically and rendered using OpenGL z-buffering, 2D projection, and alpha-blending to produce a unique and The 3D particles of each flare sub-munition are Independent control over the size and radial distribution of its signature.
