Abstract

In order for advanced image simulation systems to properly model the image formation phenomenology of remotely sensed imagery, simulations need to account for the effects of transmissive objects in a scene. These transmissive effects are important in simulating imagery of littoral scenes, vegetation canopies, meteorological clouds, and gas plume discharges. This is especially true for imaging scenarios in the long wave infrared region where very complex target- background radiational and thermal interactions are critically affected by transmission. The digital imaging and remote sensing (DIRS) Laboratory's synthetic image generation (DIRSIG) model has recently been improved to include the general simulation of transmissive scene elements. The model emphasizes quantitative prediction of the radiance reaching sensors with bandpass ranges between 0.28 and 20 micrometer. It includes spectral radiation propagation using MODTRAN, thermal modeling based on the environmental history, and extensive target-background interactions. An overview of DIRSIG's capabilities is presented along with the methodology and mechanism of simulating transmissive scene elements. Imagery illustrating the various scenarios and imaging phenomenologies are presented and discussed.
