Two schemes for the simulation of IR images of ground terrain are presented. Both preserve the statistics and power spectra of the temperature variation over the scene according to the experimental findings. The first scheme generates the scene directly in the spatial domain, while the second generates it in the spatial-frequency domain. Each is advantageous according to the simulation task needed.
