Title
A methodology to assess the impact of optical and electronic crosstalk in a new generation of sensors using heritage data
Abstract
Electronic and optical crosstalk are radiometric challenges that often exist in the focal plane design in many sensors such as MODIS. A methodology is described to assess the impact due to optical and electronic crosstalk on the measured radiance, and thereafter, the retrieval of geophysical products using MODIS Level 1 data sets. Based on a postulated set of electronic and optical crosstalk coefficients, and a set of MODIS scenes, we have simulated 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 original MODIS scenes and the crosstalk impacted scenes can be used with validated geophysical algorithms to derive the final data products. Products contaminated with crosstalk are then compared to those without contamination to assess the impact magnitude and location, and will allow us to separate Out-Of-Band (OOB) leaks from band-to-band optical crosstalk, and identify potential failures to meet climate research requirements.
