Abstract

The process of developing new sensors for space flight frequently builds upon the designs and experiences of existing heritage space flight sensors. Frequently in the new sensor development, problems are encountered that pose the risk of serious impact on successful retrieval of geophysical products using the new sensor. This paper describes an approach to assess the importance of optical and electronic cross-talk on retrieval of geophysical products using new MODIS-like sensors through the use of MODIS data sets. These approaches may be extended to any sensor characteristic and any sensor where that characteristic may impact the Level 1 products and their associated higher level geophysical products. In this study, a set of electronic cross-talk coefficients are postulated. These coefficients are sender-receiver influence coefficients and represent a system signal contamination on any detector on a focal plane when another detector on that focal plane is stimulated with a geophysical signal. The approach involves using the postulated cross-talk coefficients on an actual set of MODIS data granules. The original MODIS data granules and the cross-talk impacted granules can be used with validated geophysical algorithms to create the derived products. Comparison of products affected by crosstalk with products without cross-talk will identify potential problems.
