ShipIR/NTCS is a sophisticated and comprehensive software package that is used for IR signature prediction of naval and aircraft platforms. The code has been validated with the measured IR signature of several aircraft types including: the Bell 407; MIL Mi-17; and Eurocopter AS332 Super Puma.
ShipIR is a fully-deterministic physical model, employing the following features to model the platform signature:
- Prediction of target surface temperatures and associated radiative emissions
- Prediction of exhaust gas dispersion and radiative emissions for multiple engines
- Prediction of background sun and sky radiance;
- Prediction of atmospheric absorption and path scattered emissions, including the effects of earth curvature
- Fast 3D rendering of IR scenes, including multiple targets, full-hemisphere background, atmospheric effects, and the semi-transparent rendering of plume emissions
- Auto-calculation of solar heating, wind convection, and radiative surface exchange, including surface-to-surface and surface-to-background reflections
NTCS simulates the engagement between a missile flying in a plane, the aircraft platform, and its countermeasures. NTCS has the following main features:
- Generic imaging seeker with signal processing, point-source detection, target tracking, and missile guidance using standard proportional navigation
- Multi-flare IR countermeasure deployment
ShipIR/NTCS has the following main software features:
- A CAD translation program for converting AutoCAD (DXF) files into ShipIR/NTCS target model geometries
- A standard X-Window/OSF/Motif graphical user interface (GUI)
- A standard (ASCII) file format used for all model data input/output files
- Comprehensive error handling and message logging
- A custom script-language for batch-processing signature, detection, and IR engagement analysis
- An interactive interface for viewing the scene from any position, and for selecting what information to display (i.e. temperature scale, or IR radiance within a configurable IR band)
