Abstract

This paper describes an experiment-based model to simulate 3D infrared target in sea background. The geometric model of dynamic sea waves are based on gravity wave theory, while the sky model use SkyDome technology which takes the sky as a dome covers the land. To create the infrared images of sea waves and sky, the radiance at the detector are calculated. To acquire the radiance of target radiation, a spectrometer is settled to measure the radiant emitted by interested targets. Meanwhile, the radiant of sky is also measured to provide reference data. Furthermore, the spectrometer is used to measure the atmospheric transmission rate which is compared to the values calculated by MODTRAN. The optical system is simulated based on OTF theory. The detector noise is expressed as an equivalent Gaussian white noise. Finally, the simulation images are compared with the practical images. It has been proved that this experiment-based model produces infrared images with high reality.
