Abstract

The Navy's Coastal System Station (CSS) at Panama City, Florida has been investigating the use of multispectral, intensified cameras for standoff minefield detection. In support of CSS, Nichols Research Corporation's Shalimar Florida Office has developed a 'minefield image synethesis tool', (MIST), which is capable of simulating UV to near-IR images of minefields. The MIST software is divided into two major modules, an image generator and an intensified camera model. The image generator (IG) software performs 3D graphics rendering of objects in the scene to produce 2D images as an imaging sensor would see them. The IG models diffuse reflection from sunshine, skyshine, and earthshine. Path transmittances and radiances are accounted for. The sensor spectral band is a user input. Other quantities including reflectances and illumination sources are imput spectrally, making it possible to generate images for different spectral bands, such as those being investigated by CSS. Sensor effects including intensifier/detector response, noise, and analog-to-digital conversion are modeled in the intensified camera model (ICM) software. This paper describes the MIST software and tests that have been performed to validate the software.
