Abstract :
The pushbroom scan is done by a number of sensor elements, so it includes a sampling process inherently before resampling on the ground. In contrast the whiskbroom scan does not have such a pre-sampling process. Combining this pre-sampling process with some CCD features, for example the cross talk, the aperture characteristics, the arrangement pattern of the elements on the focal plane, the imaging performance will be degraded. The simulator system was developed to analyze and predict such a performance degradation. This system simulates the behavior of the pushbroom imaging spectrometer in one dimension; the system can describe its fundamental features
