Abstract
The Irma synthetic signature prediction code is being developed by the Munitions Directorate of the Air Force Research Laboratory (AFRL/RWGG) to facilitate the research and development of advanced weapon seekers Irma began as a high-resolution, physics-based infrared (IR) target and background signature model for tactical weapon applications and has grown to include: a laser (or active) channel (1990), improved scene generator to support correlated frame-to-frame imagery (1992), and a passive IR/millimeter wave (MMW) channel for a co-registered active/passive IR/MMW model (1994). Irma version 5.0 was released in 2000 and encompassed several upgrades to both the physical models and software; host support was expanded to Windows, Linux, Solaris, and SGI Irix platforms. In 2005, version 5.1 was released after extensive verification and validation of an upgraded and reengineered ladar channel. In 2007, version 5.2 was released with a reengineered passive channel. The current Irma development effort is focused on the reengineering of the radar channel with an expected release of Irma 5.3 in 2009. This paper reports on two of the radar modes expected to be supported in the radar channel: the fuze mode and the spotlight synthetic aperture radar (SAR) mode.
