Paper Abstract

Sensor spectral responses and their calibrations influence investigations that use satellite multispectral data. Analysis efforts to date have concentrated on responsivity calibration. A simulation approach is followed here to explore the feasibility of one technique for detecting post-launch changes in sensor spectral characteristics. If the possible system changes can be modeled with a single parameter for spectral change and another for responsivity change, measurements on only two appropriate test targets can measure and differentiate between the two types of change. The suitability of two commonly occurring terrain materials (bare soil and vegetation) for measuring possible shifts in spectral bands of five sensors (MSS, TM, AVHRR, CZCS, and HRV) is assessed. Effects of sensor noise are included in the formulation.
