Paper Abstract

A radiometric math model (RMM) has been developed for use as an analytical tool to establish design requirements and to model performance of the moderate resolution imaging spectroradiometer (MODIS) instrument design. The MODIS instrument is scheduled for flight on the first earth observing system (EOS) AM spacecraft in mid-1998. The model represents a significant advancement in the state of the art in radiometric simulation techniques. Characteristics of the MODIS optical design, focal plane assembly (FPA), scanning and electrical parameters, and the on-board calibrators are input to the model as predicted, estimated, or measured. Primary outputs of the model are radiometric sensitivity [signal- to-noise ratio (SNR) and noise equivalent temperature (NE(Delta) T)] and radiometric accuracy. This paper describes the theory of the model, the input and output parameters, and the major program modules, and presents predictions for the current MODIS design.
