ABSTRACT
Simulation techniques may be categorized by the method used to model each of these elements: the scene model, the sensor model, and the processing model. Most sensor simulations start with an input scene model containing targets, backgrounds, and possibly atmospheric effects. Initially, the authors discuss some aspects of the sensor model including the optics and focal plane. In the main body of the simulation, each pixel is examined to determine if it is near enough to a point source to access the convolution table. The procedure used for developing the noise model for the simulation was to first find a mathematical formula which reproduces the supplied noise data, satisfactorily interpolates between the data points, and extrapolates in a reasonable way to the lower frequencies of importance for the processor. The continuous dose-rate an exposure simulates a postnuclear radiation space environment.
