Abstract
A push-broom imaging camera with time expansion, selected for its ability to generate images with high resolution and high radiometric signal, is described for accurate site certification from space. The system providing the high-resolution imaging requires a sensor with an increased dwell time to generate a high radiometric signal. This may be accomplished by pointing the camera at each pixel for a longer interval of time than that available due to the sensor motion in the push-broom imaging configuration. This is referred to as push-broom imaging with time expansion. The use of the camera with time expansion may be applicable to any remote sensing imaging problem that requires simultaneously high spatial resolution and a high level of radiometric signal. For surveying a Martian landing site, it is necessitated by the imaging from an autonomous orbiting sensor whose speed is determined by its orbit and the planet’s mass.
