Abstract

A simulation approach for the performance evaluation of both scanning and mosaic infrared sensor systems and their associated signal processing is presented. This approach allows a parametric exploration of design alternatives and environmental extremes. Various focal plane geometries and alternative signal processing algorithms can be investigated. The simulation has been implemented for maximum efficiency to allow the evaluation of system probability of detection and false alarm. rates. Microscopic effects, such as optical crosstalk, image motion during the dwell, assymetric point spread functions, and platform effects, are modelled. Important models within the simulation are: optics and detector, Time Delay and Integrate (TDI) and Charge Coupled Device (CCD) effects, object motion, and a band pass filter. The output of the simulation can be input to alternative data processing algorithms. Individual algorithms and configurations can be evaluated at several stages in the flow. The simulation has been configured to model both staring mosaics and scanning bar sensors. Data supporting model verification and an example of the application of the simulation to a scanning infrared astronomical satellite are discussed.
