Abstract : The SHARC Image Generator, SIG, provides the user with the ability to generate synthetic non-stationary structured infrared (IR) scenes using the Strategic High Altitude Atmospheric Radiance Code (SHARC) computations. SIG is an integrated set of program modules that provides a host of options for rendering stochastic LIMB, NADIR, and Off-NADIR structured images. SIG employs an interactive menuing front-end that allows the user to specify sensor pixel size, resolution, aspect, and viewing geometry. It uses SHARC parameter output files as input specifiers. SIG employs power spectral density (PSD) function filters whose parameters may be specified by the user or by SHARC. The filters are processed using a combination of classical and parametric digital spectral synthesis techniques.
