Paper Abstract

Modeling of visible band line scan EO sensors in the flight test scenario involves the computation of ground resolved distance (GRD) based on the minimum resolvable delta- radiance (MRDR) criteria for visual perception of tribar targets on an output display device. MRDR is driven by the basic sensor parameters of noise equivalent delta-radiance (NEDR) and modulation transfer function (MTF). Therefore, the modeling process can provide a sequence of steps to reveal the linkage from the basic sensor parameters that produce NEDR and MTF, to expected lab measurements, and then finally to expected GRD performance in the flight test scenario. The MRDR vs GRD curves reveal the EO sensor sensitivity to parameters such as sun elevation, target reflectivity, visibility, and aircraft ground velocity. GRD is not a single fixed value but rather exhibits variability based on both observer statistics and flight test scenario factors.
